hi
not sure if this is to do with your mods but here goes everything was allright untill i installed bob logistics and shinybobgfx updates (including fixes) but when i do a blueprint with express filter inserters thery appear as question marks. - if i have the blueprint in my inventry and place it down it is ok
any help would be appreciated thanks
p.s. - running with bobs and angels mods

Sounds like the migration that's supposed to convert things to the correct format failed to be triggered.

my mods have basically been suffering from an issue where, because I didn't use the base game inserters, vanilla blueprints had issues, such as wires and filters being deleted.

I've basically implemented a long overdue fix for it, and it worked fine for me, but it doesn't seem to have worked for you...
