Registration issue

The two frames at this link don't register properly.

To reproduce:

• Create a sequence from the frames
• Apply plate solving to the sequence (don't skip already registered frames); check the "use as registration info" box
• In the registration tab select Apply Existing Registration.

The following error appears:

22:47:07: Registration: processing using method: Apply Existing Registration
22:47:07: Interpolation clamping active
22:47:07: Processing all images in the sequence (2)
22:47:07: The reference image has a null matrix and was not previously aligned, choose another one, aborting

If stacking with the max framing option is done anyway (overriding the warning that appears) the images are not correctly aligned:

When this occurs I notice the frames don't get the green outline that indicates they have astrometric registration data.
