V15: MNTP retains entitites when switching node type

[nikolajlauridsen]

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

V15/dev-207bd728

Bug summary

If you create a piece of content with a content picker (MNTP), pick a piece of content, and then change the node type, the picked content will visually disappear, but will still be included in the request send to the server, however now with the "Type" set to the new node type, for instance "member".

Weirdly, if you remove the picked member, and switch back to content, the content now has the "Type" set to member, and you have to re-pick to clear this.
