renumbering not working in STAAD

I've been experiencing this in many projects, renumbering is not functioning at all. I get the message that xxx plates were renumbered successfully but looking at the plates table everything is the same.

I tried all options ascending and descending with no hope. Another thing to note, let's say I have 8599 plates in my model, if I choose to renumber in descending order starting from 8599 I get an error that renumbering is resulting in negative values and hence 0 plates renumbered.

I think the problem is also with members, nodes and solids.
