Problem with vacuum control valve PID loop

Hi, our vac controller set point used to be selectable in a range from 0 to 1.5bara.

The pv_scale is still 0 to 1.5 but since a download we are now limited to 0 to 1, if we select higher than one, say 1.25 then it quickly takes the sp back to 1.

All of the scales I can find are from 0 to 1.5 and yet on the faceplate pv_scale there is a small white arrow, indicating that we cannot go above 1.

Any help is much appreciated
