Bug Description

The graphical installer fails to format encrypted partition if you try to set up more than one and explicitly mark it all for formatting, and then it acts surprised when attempting to mount unformatted junk data as ext4 and aborts.

You can see the setup of the disk in the attached screenshot, with both sda5_crypt and sda6_crypt clearly set to be formatted.
You can also see the popup fails to recognize the formatting of sda5_crypt.

Unsurprisingly, if I click "Continue", I get a pretty much instant mount failure of sda5_crypt and it aborts.

I tried rebooting, deleting the whole encrypted partitions and setting it up again the same way, same result.

I tried the exact same setup in the text-based installer in expert mode with the custom partitioning - and it works perfectly fine.
