After updating, sometimes can't change objects inside frames in themes

In the 4.5 version, sometimes I can't change some objets inside frames. When I click to chose them, the configurator selects the whole frame, and there's no way to select the object inside. That's pretty critical, because I can't change important features of my visualizations. Could you check it? It doesn't happen always, but when it happens, is very annoying.

Thank you!
