Amateur hour ^^^^. Sorry about that. Hopefully everything is OK now.
Thanks @lmulhall-phet. @ariel-phet is this something that needs to be addressed?
You're welcome @jessegreenberg. I know it's a small thing, but I'm not sure what I should and shouldn't point out yet.
@lmulhall-phet I think everything should be pointed out, I appreciated it! I just want to make sure @arouinfar and @ariel-phet agree it is worth some time. Though I agree it does look like this could be a quick thing to change. @arouinfar @ariel-phet thoughts on @lmulhall-phet suggested fix?
I would move the "Sum of Forces" text and the sum of forces arrow up, and I would move the "Applied Force" and "Friction Force" texts and their respective arrows down just a bit.

Agreed! Thanks @lmulhall-phet.
I would move the "Sum of Forces" text and the sum of forces arrow up
That would fix the occlusion problem for most situations, except for when the fridge is on the bottom. ("Sum of Forces" would overlap the mass.)
and I would move the "Applied Force" and "Friction Force" texts and their respective arrows down just a bit.
I think these vectors are purposely aligned with the pusher's hands, so that the applied force looks like it's coming from the pusher. Generally, the vectors would be drawn from the center of mass, but since this sim targets a younger audience I think it makes sense to keep them aligned to the hands.
Perhaps we could instead try reducing the opacity of the vectors a bit so that the occluded values could still be read, such as the "50 kg" in this case. It's not a perfect solution, as the Force values (if turned on) would occlude the text behind them, but I think it'd be an improvement.
Any thoughts @ariel-phet?
@lmulhall-phet just reiterating, I think in general always good to point out what you find. As a rule of thumb, anything you think could be a bug OR a hindrance to student use is worth pointing out. We can always discuss or say "yes this is a known issue" or such, but in general we really like QA to take ownership and point out what they feel is potentially an issue.
In this particular case, it would be difficult to find a position for the vectors that would accommodate all situations. More importantly, I think that no pedagogical issues arise from this occlusion. It is easy to get the mass information before the experiment, by stopping any application of force, or by grabbing one of the objects. I think being able to see the mass label during pushing or such is not critical.
Closing.

Problem description:
The sum of forces arrow overlaps with the x kilogram text when sufficient force is applied. The applied force and friction force arrows just barely overlap with the x kilogram text. Found this while testing PhET-iO in the simulation wrapper. Should be an easy fix. I would move the "Sum of Forces" text and the sum of forces arrow up, and I would move the "Applied Force" and "Friction Force" texts and their respective arrows down just a bit. This is for phetsims/QA/issues/42.
