J has a fix internally, but I don't know when it will be released.
We were trying to harmonize actual ship storage with the tooltips, and used some defaults (10) for a system that was never rolled out to the individual ships. That system would have had unique storage for each ship which while a thing we could do, is maybe not a thing we should do.
Anyway, no change to functionality is intended. The limits described for each ship (30 for SW for example) are coming back soon.
