So this problem has been marked as solved and it looks like it has reappeared again. My project as an example: [https://x.thunkable.com/copy/e26e2d5cd1c3205d4d48f48e34bbfb95](https://x.thunkable.com/copy/e26e2d5cd1c3205d4d48f48e34bbfb95) Essentially, when I look at my variables, it appears that old variables do NOT get deleted. In fact in my pull down ‘select the variable name’ in the variable block, I have a new AND an old variable that share the same name. I believe my code is getting confused (I know I am) and sometimes looks at the old variable. There is no ‘delete’ on the pull-down that seems to have existed in the past, though that seems to be an ugly fix. Another weird feature: variables that don’t have the create block still exist and can be used. Seems like there should be a ‘garbage collection’ function that runs every time it saves. Easy for me to say, I don’t have to write/debug/maintain the code. This was marked as solved and explains the problem: [[Solved] How can we delete function type variables no longer in use?](http://community.thunkable.com/t/solved-how-can-we-delete-function-type-variables-no-longer-in-use/563743) PS: To the developers: Thanks for all the hard work. We only complain because we see how good this product can be. Thanks again! ---
