In doing a manual install, I always format the '/' root partition, but leave all others alone.
Thus for all others, I kept the partition edit option at "Keep".
After changing the partition for '/' to "Format", I noticed that there was no display column for "Format?" as there is for gparted, to see at a glance which partitions were to be formatted.
Therefore, I went back and edited the partition, and found that the option was no longer "Format", but had reverted to "Keep".
I tried several times to change it to "Format", and each time it reverted to "Keep".
When I decided to go ahead with the install anyway, I was presented with a list of tasks to be effected, the first five (!) of which were "Format sdb_ as "/" (or some such wording).
I hope that it did not actually format the partition 5 times (but it did seem to take a while!).
