"Disk Size too small"-error with same size drive

[Ikanno]

Hey guys, I'm not new to unraid but fairly inexperienced relating Unraid. Currently I have a set up a 2TB HDD drive for data and a 2TB HDD drive as parity. I want to swap out the data drive for two 2TB SSDs. I precleared the SSDs and now have the problem that I get the "disk size too small"-error when I try to assign one drive even it being the same size. I attached some screenshots.

Has anyone experienced this problem?

Unraid has the partitions starting on sector 2048 for SSDs vs 64 for disks, so there's a little less space and you can't direct replace a disk with an SSD of the same capacity, you can create a new array and manually copy the data though.
