Version 8.2.1 of Storage Drawers for 1.16.3 of Minecraft

While the recipes for the upgrades appear in JEI, and you can even make the upgrade template, you cannot create the actual template. https://i.imgur.com/sOlLihf.png.

This must have been fixed at some point, or it was never an issue .. could have been a pack or mod conflict issue

Unable to reproduce
Are you still having the issue?
Have you tried on 1.16.5?
What other mods do you have installed?
