Do you have some specific examples of how you have put together a page (e.g. a Content Template designed with Divi) and the required settings to be able to reproduce the problem?
Note that we have particular guidelines about how to use Divi with Toolset and some known styling issues that arise.
If you are following those guidelines and the site design has changed because of a Divi update then I will look and see if we need to update that advice.
thanks for the hint with the guidlines - I will check them and see if it helps. However everything had survived the recent few updates until Divi 3.10, so i hope that i'm not the mayor cause for this ... 🙂
I will keep you updated soon and send you some more detailed info's
