I am having trouble with the breakpoint table conversion in an analog input record.

The definitions of the offending records are attached below. 

EPICS versions tried are 3.14.9 and 3.14.10.

"calib1" is  an ai record of type "Raw Soft Channel." 

It should convert its raw value via the .LINR = typeKdegC breakpoint table. 

Instead, VAL is equal to RVAL and STAT is "Soft."

"calib2" is a copy of "calib1" but uses .LINR = LINEAR.

It works fine.

Theyr'e both shown in this CSS screen shot:

Any help or suggestions is greatly appreciated.

Thanks,
