No more context option "open with" with more than one file in Bridge

Hello together,

since Bridge 10 i no more can open a bunch of selected jpgs or every other types with the option "open with" in context or in the dropdown menu "file"

I can open only 1 file with that feature, if i select only 2 the context option "open with" is gone or greyed out.

This drives me crazy while i do this the whole day and i can see no reason why this elemantary feature is gone?

Can someone help me out with this?

Thanks and regards
