Lovelace Views - Linked / Duplicated Problem

I’ve been using HA for a couple of years but am certainly no expert, however I thought I’d got conversant with the basics of Lovelace Views - Wrong. Something is seriously wrong with my views.

I had a view called Summary which comprised a lot of badges, graphs and so on. Another of my several views is called EV for electric car stuff.
The EV view suddenly became a clone of the Summary view a few weeks ago - lost its own content and displayed identical to Summary.
Today I foolishly attempted to delete the EV view and it has erased the Summary view entirely yet left the EV view, albeit empty.
I’ve added a new view called Summary and now anything I put in that view is replicated on EV.
Interestingly Summary can be moved left or right as normal using the arrows. EV arrows cause the Summary view to move whilst the EV view stays put.

Seems like some sort of corruption to me but how do I sort it out?

did you configure lovelace via the ui or in yaml?

do you have any backups of you config from before the “corruption” occurred?

Only ever done the config of Lovelace in the ui.

Have various backups but didn’t notice this problem until recently so I’d be losing a load of stuff if I had to roll back to before the ‘corruption’

BTW all HA up to date.

Sorry that I can’t really help then.

I only use yaml mode.

If you can’t get it sorted out otherwise you might have to resort to restoring a back up, unfortunately.

Thanks. I’ll keep trying to get to the bottom of it.

Backup has taken me back to where I was but I’m restricted in what I can do on development.

Will try building a new dashboard and ensure that doesn’t exhibit the same issues before I get too far
