Hmm I forget what was on this drive. I used to have Windows 10 on it, 
then I can't
remember. I may have installed Arch Linux on it. What ever was on it, I 
just ran the
installer letting it do it's thing selecting Encrypted root with LVM 
because I wanted to
see if that worked. it didn't, then I tried the default, before posting 
the bug report.
Finally I went though with Miguel's patch selecting all the defaults and 
that was
the result.
I feel the installer should not care what was on the drive to begin 
with, it should just
format the drive how it sees fit. Why should the existing contents of 
the drive
affect the outcome when we are reformatting everything anyway?
