Accidentally clicked on expand RAID

Hi I accidentally started to expand my RAID on my PR4100. I have 2x18TB in bay 1&2 and 2x16TB in 3&4. I meant to swap them around so that the 16TB’s were in the first bays before I started. It wants a new drive in bay 3 but I don’t have another 18TB to continue the process. Is there a way to stop the expansion process?
