Homescreen bookmarks impossible to remove

Hello,

I have an iPhone X on iOS 15.6.

It appears that two of my Safari bookmarks on the homescreen are impossible to remove. There is simply not the usual option to remove them when I maintain my click, as you can see on the picture (don't mind french language).

I already looked up on the internet but I found no answer. It is not a problem of Screen Time (I have no restriction activated), and it is not possible to delete the apps via iPhone storage as they are not even in the list.

I tried creating new bookmarks for these same websites and it appears I can delete the new ones without any problem. But still not these two.

I hope somebody can help me with that.
