It appears I cannot use bamboo shoots in recipes at all, for recipes relating to this mod. Or at least, JEI is showing that.

Edit: It appears you forgot to rename the bamboo shoot item in a lot of things.

This issue is marked as Fixed, but I have the same problem (tropicraft-MC1.12.2-7.1.1.56) which is the most recent version uploaded.
As a result, I tried an earlier version of Trop (tropicraft-MC1.10.2-7.0.3.145) but had problems with that too (logged as an issue).
I'm desperate to play this mod .............

It's not fixed until these changes are merged.

Ahhh ..... sorry. I'm not familiar with how these things work.
I saw a spotlight on this mod and have been dying to play it - looks fantastic :)
