Strange capacity warning 5C

Sad Strange capacity warning 5C
Bought a Drobo 5C a month ago, set to have dual disk redundancy, and populated with
4x 1TB HDD (different brands/models)
1x 5TB HDD
Sure, a strange combination, those are all spinrite recovered drives from older systems, and they all are still perfectly fine according to spinrite.
Now, it got fuller the past week, so I understood why 1 of the 1TB drivebay leds started turning yellow due to 'running low on protected space'.

So I replaced the 1TB bay that had turned yellow with a 4TB disk I had left from a recently upgraded system somewhere.
The drobo took 3 hours to have it implemented in its beyond-raid.

Assuming the extra (newly added) 3TB would make some more space available, give some room, it disappointingly did not! Very much to my surprise. No idea what kind of RAID this is, but adding 3TB to a 5-bay RAID would *at the very least* make the system all-green again. Especially after 3 full hours of re-syncing the raid.
Now another one of the left over 1TB HDDs has the yellow LED, with the exact same capacity warning.

I did not expect this for this price, to be honest. This has me thinking about returning/selling this drobo, and replacing it with something else..

I did some calculations and for the same price I could easily buy 2 new 5TB drives, mirror them in a new 2 bay raid box and have practically the same security feeling as I do with this 5C. The chances that 2 new (spinrite tested) disks fail at once in a new 2-bay unit are lower than 2 disks failing at once in this old disks in my 5C. Plus it's a lot faster using 2 bay mirror raid, easier to recover when the unit itself fails too.
I wonder how I fell for this drobo trap.
