Hi @miguelmoreno 

It is possible that having documents open that use shapes from the library you’re trying to delete could cause issues.

Can you ensure and give a try after refresh / from a different browser.

Hope this helps - Happy to help further!!
Thank you very much and have a great one!
Warm regards

Hi @miguelmoreno, 

Could you try opening your document in a private or incognito window to help us narrow down the potential cause? Could you also try connecting to a different network or disconnecting from your VPN (if applicable)? Sometimes account performance issues can be related to internet security/speed or browser issues. These steps will help us eliminate that possibility. For help with opening an incognito window, please see this community post (in English).

If those don’t resolve the problem, can you please send the following information so I can take a closer look?

• A screenshot of the issue.
• A screenshot of the associated Javascript Console output after reproducing the issue. You can open your Javascript Console by pressing Ctrl+Shift+J (if your computer is a Windows/Linux) OR Cmd+Opt+J (if your computer is a Mac).
