Mysterious popup shown instead of conflict resolution window

[quasipedia]

When I try to resolve a conflict and I right-click on the note and select Resolve Conflict this comes up instead:

Joplin 2.12.15, running on Linux.
Conflict Resolution v. 1.2.3

OK you have delete the original, this is why you geht this error.
The error message should be adapted-

Hej, thank you for the timely reply. Got to answer only now, apologies.

I am not sure I'm following: should I "delete" or "delete not"? And "the original" refers to the local or remote version of the file?

Oh a typo on the hurry ...
You should not delete the notes until the conflict is resolved. The plugin can no longer compare the version in the conflict folder with the original.

This seems to be fixed in Joplin 2.14.11 (Linux/build from commit 582f0853bb4a7e389daec03bce1682d910da267b).
