I’m unable to delete a customized card in my workspace. Every time I remove it and save, it says no changes have been made. Then, when I refresh, the card reappears.

I’ve reviewed the doctype and confirmed that the card is no longer in the “Home” workspace, yet it still continues to appear.
I checked backend & same issue. It’s not on DB
Have any one you encountered this & are there any possible solution?
Thanks in advance.
