Adobe Portfolio

I'm trying to setup a portfolio but I keep getting this anoying error message whn I am in a gallery and I want to add a Lightroom Album : "Your album(s) has already been imported".

On the settings on the left, Pages, the page I just tried to import does not appear anywhere.

On this same page there is a big blue plus sign at the bottom of the page but I get the same error message.

In integrations, the LR album I tried to add doesn't appear in the list.

What should I do ?

Thanks
