Hi Ayoub,
Thanks so much for your report!
Go to Bricks » Settings » General and start the orphaned elements review and remove them. Orphaned elements containing an icon may be found there. This is the most likely cause of the problem.
If this does not work, please send temporary login credentials and a link to this thread to help@bricksbuilder.io using the email address you used during the purchase.
Best regards,
