Description of problem:

When installing a system (KVM) using the GUI, the following scenario leads to having LUKS1 devices hosting the LVM VG:

1. No click on "Encrypt my data" in INSTALLATION DESTINATION
2. Clicked on "Click here to create them automatically"
3. Clicked on "Encrypt" in CONFIGURE VOLUME GROUP

This results in:
- LUKS Version was grayed out
- Encrypt checkbox near Device Type was grayed out

After installation, the system ended up having LUKS1 (I intentionally created 2 VGs, one for "root" and one for "home"):

I wasn't able to perform a similar setup with LUKS2 instead. The only way to do that was to reinstall using a kickstart.

Additionally, installing a beaker system (dell-per740-04.khw2.lab.eng.bos.redhat.com) similarly, I ended up having 2 LUKS2 devices, but the kickstart showed 1 LUKS1 device and 1 LUKS2 device:

Version-Release number of selected component (if applicable):

anaconda-29.19.1.13-1.el8

How reproducible:

Always, see description

Additional info:

This is somehow related to BZ 1759972. Please consider both simultaneously if possible.
At least, while in the GUI, the summary (see attached pictures) should state the LUKS version that will be used.
