Hello,

My version is as following:

• HEI: v4.22.0
• CraftTweaker: v2-1.12-4.1.20.675
• Forge: v14.23.5.2860

Detail of the Issue:

I've used JEI.removeAndHide() and then use JEI.addItem() on many items. There are no errors or anything like that.
The items wouldn't show up in HEI with the new recipe. I also click on the item to see the recipe (it works just fine)

I also run this problem with the older version (JEI, not HEI). Same result.
