sharepoint online – Remove spfx webpart

I’ve uploaded and deployed some spfx webparts through my App Catalog site.

Now these webparts are not useful anymore so I’ve deleted them from the App Catalog.

Then I’ve checked my sites and modified modern pages and I’ve seen that these webparts are still listed even if they were deleted and even if they are not listed in site contents page.

I’ve also waited and re-check after a week, but webparts are still listed when I open a page in edit mode.

Is there some step I’m missing?
