Bar Chart with thresholds - completely colored now?!

Hi,

after the last update (9.3.1, maybe 9.3.0), the bars of my “Bar Chart diagram” are now completely colored and not devided into the thresholds:

PRIOR the update, a bar from 0 to 100 was blue/green/yellow/orange/red
AFTER the update, the bars are now completely “solid” colored.

Any change to get the “devided” bars back?
