Fedora 34 install fail

First time trying Fedora since I used it at version 5. I could document this better but I’m not because it’s tedious, and won’t accomplish anything. Suffice it to say I couldn’t place my two disk mount points on different devices. On the 1st panel I could select the 2 different disks I wanted to use…my SSD (sda) for root and my larger HD (sdb) for /home. But after selecting “custom” storage configuration the “+” on the next screen there was no way to select which drive to place which mount point on, everything defaulted to the SSD. I read somewhere to use Configure Mount Point to change the device. But that option wasn’t available!
