Folks I am a bit new and not sure how to treat the flipped data.  I know I saw this somewhere in fundamentals but I do not remember how Adam treated the data.  Last time I. encountered this I was at 58 of 60 and just dropped the last two.  Last night it was at 10 of 25 so I have to do something.   I was shooting Orion's Belt when it flipped.   One min the flame Nebula was on the lower left then after the flip the upper right.  If I was shooting raw files I would just go into PS and flip the files and go on but here I a not sure what to do.   Can someone offer some advice?
Thanks in advance for your time and trouble.   Here is the google drive links to #10 & #11 where they flipped.  not processed
