Inconsistent focal length value(s) - metadata not generated

[aworonow]

In the last year or so, I've never run an image integration without getting the above WARNING!
The fl of the singular instrument is specified in each subframe: "FOCALLEN | 3367.0". How do I eliminate that warning?

I will see this occasionally, usually when I make a small change to the equipment profile between sessions.

It is not all that important, all it means is that the image capture details will not be included in the image fits header.
