How to reproduce:
1. Download attached project file and open "Report" Scene (Check that the particle system has a circle shaped emission with loop mode and that there's a warning about the Particle System Culling being disabled because of this animated shape)
2. Change the shape to Edge and mode to Random (the warning is still shown which shouldn't be given that this is not an animated shape)
3. Change again to Circle and the mode to Random (the warning disappears)
4. Select Edge again (now the warning is still gone, as expected)

Expected result: I would expect the Culling system to honour the currently selected shape and mode (edge+random) no matter what other shapes' animation mode is (circle+loop)
Actual result: When selecting a non-animated shape emission, like Edge w/ Random mode after having an animated emission shape (like loop mode circle), the Particle System Culling is disabled in spite of having a non-animated shape selected
