Prevent ignored files from coming back in error after some time

On the Intranet, I have the following folders synchronized:

1. https://intranet.nuxeo.com/nuxeo/ui/#!/doc/664b232f-8db3-4825-9827-b94c21cc7c55
2. https://intranet.nuxeo.com/nuxeo/ui/#!/doc/f478eaa1-6796-43fc-ac4e-52ba4f0a5cb3

In these folders, some Documents have the same name, which leads to errors on Nuxeo Drive.
I chose to ignore them, as we can see in the enclosed screenshot, yet after a few days, they keep coming as "Errors" and I have to ignore them again.
