I took a series of photo for a time lapse video. I was using "Av Mode", "Timer", then F11, ISO 200, auto shutter. EOS RP, RF 24-105 F4, IS OFF, MF. It was during sun set and blue hour. Later I checked the photo, and the aperture changed automatically...

I cannot find in lightroom the corresponding correction profile of RF 16 2.8 lens. Maybe my LR is outdated. Is there any other correction profile which is suitable to use?
