I am just starting out (so have not jumped into local hosting yet) on Odoo v18.4 and in the middle of replacing my current CRM. I have exported the data then imported it successfully so I have a healthily populated CRM on Odoo.

Kanban and List views working right (the only other views I'm using), but trying to create a graph view I've ran into a problem in Odoo Studio. Any time I try to have both a First dimension and Second dimension filled in I get the following messages:

(Prompt in the top-right corner)

"This operation caused an error, probably because a xpath was broken"

(Popup in the middle on the screen)

"Validation Error"

"Error while parsing or validating view:

Element '<xpath expr="//field[@name=&#39;date_deadline:month&#39;][not(ancestor::field)]">' cannot be located in parent view"

This happens no matter what Type of graph I use or what data I select. Originally, I had First dimension filled in and I get the error adding a Second. However, now the opposite is happening: I can fill in the Second but I get the error adding a first. I didn't have a backup database at the time. Is there any way to fix this on Odoo Online or is local hosting required at this point?

Thanks much.
