Can't install on existed partition

My existing partitions:
sda1 - 2G swap
sda2 - 16G / Centos7
sda3 - 16G formated(ext4) or deleted
sda4 - 900G+ /home
-
Manually partitioning show 16G available space on disk correctly.
Then click + to add partition with / mount point, enter all available space 16G and get not editable field with /dev/sda5 in it.
Then click done and message warns:
1. sda3 will be deleted
2. sda5 will be created
I'm afraid to continue
Edited after 2 days

Can't believe, but problem disappear just mysticaly today. Sorry.

Where is your /boot?
I would like install new Centos 8 with root and boot on /dev/sda3.
Old Centos 7 with root and boot exists on /dev/sda2 and swap exists on /dev/sda1.
I will mount existed /dev/sda4 to [sda3]/home manually after Centos 8 installation.
So, I would leave /dev/sda2 as Centos 7 copy (configurations.. etc.) and I will install Centos 9 on it (/dev/sda2) in the future.
PS
I've try to set /dev/sda3 active, deleted or formated from console for Centos 8.

Ok. There is a partition.
Do you select that partition (instead of trying to add new) in the installer, set "mount point" to '/', choose "Reformat", and "Apply"?
