Current Behavior

I currently can see the Give Plugin menu count is not coming proper and also the list of the plugin that is being shown is also not the same

Expected Behavior

I expect the menu count and the list of the plugin show should be perfect

@Sidsector9 See if you can recreate this issue by installing Give core and Stripe add-on and then check and see if Give (2) displays correctly at the top of the Plugins page. If it does not, take steps to fix it and try to recreate with more add-ons.

@kevinwhoffman What should be the correct author? GiveWP or WordImpress?

@Sidsector9 Update the logic of the filter to display all plugins that start with Give -. This is the only way to display the expected results without changing the author of several add-ons.
