Storage pool capacity incorrect despite correct capacity detected.

[chtcgdtms]

Hey there! The title lays it out plainly, but to expand on it,

I am using a TS-453Be on firmware QTS 5.2.5.3145.

I recently replaced two of my drives (6TB drives → 18TB drives). The rebuild went great, with each drive being properly detected by the NAS, showing their correct 16.37TB capacities. However, the Storage Pool still shows the original 5.45TB capacity from before the upgrade. I resized accordingly, and my network sees the correct total capacity, even though the NAS storage pool does not reflect that. That said, despite the correct capacity shown on network, I cannot add any data beyond the original 5.45TB threshold.

I have looked all over the internet, and have seen many people with similar issues, but none of the solutions I’ve seen have been able to resolve mine. I’ve been attempting to figure this out since Monday in my free time to no avail. I would greatly appreciate any and all help, and can provide whatever other screenshots or information you need. Thank you very much for any assistance you are able to provide me.

EDIT: Adding image.
