Match Total Exposures – Error

[P.C. Normann]

Hello!
Does anyone know of a solution for this error message in Develop settings/"Match Total Exposures"?

Ligtroom Classic Release 12.3, Camera Raw 15.3, Apple M1 Max, MacBookPro, macOS Ventura V. 13.4

You can get that error if the photo is missing EXIF shutter speed, aperture, and/or ISO.  Select each of the photos in turn and look in the Metadata panel to ensure that LR is displaying values for those fields.

Thank you very much for your help, that's where the problem was hidden due to the missing metadata.
