Deleting flows

Happy New Year to you all!

I have great difficulties when using the information window to delete multiple flows. Everything works as expected until I press Apply, after which Dorico either hangs forever (or at least longer than my patience allows) or cancels the operation, which is to say that I can press Apply again, which brings all the deleted flows back…
I can rearrange flows pretty much as expected, although it takes a bit longer than I’d have thought, so my workaround is to put the flows I need first in line, and then only print until there.
Is this a known problem? I couldn’t find it mentioned in the forum.

How many flows do you have, and how many are you trying to delete? If you would like us to look into the problem, please attach the project here (zip it up first) and we’ll gladly take a look.

Thank you, Daniel. I’ve sent you a mail with the project attached.
