Initial bounds entry stays selected in tasks tab components box even after it's deleted.

[charlieb]

I had deleted and recreated the bounds in the UI a couple of times to get it to actually fit the model. When I try to generate a toolpath I get the following:

Failed to find item in collection (CollectionName.BOUNDS): None (expected: ['f13664e3f09b423cb0cdf3c452c971d9'])
