Problem

on 1.20.1 fabric metro windows have the same recipe as corrugated metro casing.

Potential Solution

make the crafting recipe of metro windows also have a glass pane

Noted, thanks for the issue!

Same issues for 1.19.2. I actually had planned to fix it in my modpack through KubeJS. Good that @bangetto created the ticket. Thank you.

I think I found the root of the issue, in the recipe you use the tag of fabric:glass, which doesn't exists, it should be replaced with c:glass_blocks

bc the tag currently in use doesn't exists JEI/EMI probably ignores it, showing the player the recipe of the corrugated metro casing.

closing, since the pull-request fixing it was merged
