I can't seem to craft within modular storage tile entities and in one of my storage modules I only see 17 items, but it has ~190. I can access those items within the scanner.

You may have typed something in the search box?

Show a screenshot?

Ah yes that was dumb, sorry!

Oh but, My storage modules still won't craft. Only my scanner. Do you have any idea what could cause this?

I made a small video demonstrating it.

Thank you for taking the time to create this issue, as we're no longer supporting versions below 1.12, I'm going to go ahead and close it but if this bug seems to continue over to newer versions, please do report it again so we can investigate the issue further.
