I have been struggling to Import a newly developed App into our Production environment.
The Import no longer works. It fails every time with multiple errors. The only way I could get it to work was to delete all the flows that already existed altogether and set it to Create as new. Now, when I go back in, all the original flows are still there, even though they had been deleted.
The new ones have been created with -2 and -3 after the name, which is absolutely useless. The window for selecting the Flows into the App is not large enough to see all this.

This is what it did. After Deleting, the Flows were all still there, but turned off. The problem has since gone away.
If you are unable to delete, you can "Turn Off" flows if not required.
