Switching SD cards between A9 and A7RIV ok?

The other day the SD card I was using on my A9 was full, so I swapped over the SD card which was in my A7RIV.

A message then appeared on screen along the lines of 'preparing image database.'

Later I noticed several dozen blank images (plain grey) when I imported the files into Lightroom.

I couldn't work out whether any of my pictures had been deleted, or whether the plain grey images were 'extra' ones written to the card.

So is it safe to swap cards between Sony cameras? I never had a similar problem with any of my Nikons so I did it without paying a second thought.
