Here almost the same problem. The View II displayed:
EH: 148l 180 days
EH: 149l 180 days
EH: ***l days
EH: 349l 180 days
EH: ***l days
EH: 349l 180 days
So it toggles. The filter keeps (fortunately!!) running.
After a reset of the filter the status in PLC changes between 'unknown' and 'normal'.
View II toggles:
EH: 316l 180 days
EH: ***l days
Btw, what does '180 days' mean?
