Education beta items glitched after switching out of Education mode

hello mojang. the past year a glitch when turning off education beta has not been patched. this glitch is causing world corruption crashes and many more. after putting items that are only in education in a chest then turning off education some items like glow sticks elements heat blocks and many other will become invisible or have missing texture in the inventory. the names will also have title.name in them showing that its a corrupted or glitched item. i have been collecting finding and reporting bugs. also if i have education beta on and my friend in the same server does not have it they will see a missing texture and sometimes if they pickblock or try and break it the game crashes. now i love collecting illegal items and bugs but im just worried that other players wont know the dangers or accidently corrupt their world. thanks mojang for everything even if its not supposed to be there. i can see this issue being reported but i can add on

steps to reproduce the issue

1.Make a new world or join a world

1. Enable education(beta) in settings

2. place items that are only in education in a chest or place it in the world

3. disable education in settings

5. notice that some items are glitched or missing texture and that they cause crashes and lag over time

expected result

1.all items stored that are not in the code outside of education are removed

1. all blocks placed that are only in education should either become unknown or be removed

2. the items and blocks should not cause crashes/corruptions

3. a warning should pop up before you enable education

actual result

1. some items that are glitched and are only in education stay

2. all blocks placed that are only in education ex heat block become missing texture and stay in the world able to be pick blocked

3. most items have a high risk of corrupting and causing crashes.

4. no warning for toggling on or off education

most likely a bot will reply but if not i do have a video of these items and more glitches in 1.21.131(it is low quality sorry)
