Beta 35: Settings of my own formats in compiler are gone

Compiling a Beta 34 project in .doc format worked fine a few days ago. Replacements were working, everything was okay.

Compiling the same project with Beta 35 failed. All settings of this saved preset are gone. No page break, no replacement of <$label>, Chapter heading missing because the assignment to section layout is gone. Page margins, page layout, everything is broken.
Instead I get a popup to import v1 settings. I don’t use v1 anymore, since two years or even longer!

I didn’t change a thing in the meantime, just doing the update.
