Invalid parser warning

Warning: Unknown current: I(vibq2)
Warning: Trouble parsing .meas ibq2_pulse find i(vibq2) at=1.5m

The objective is to measure time-domain differences with various RC combinations connected to LTP inverting Q2 transistor-base. The curious thing is the Viewform outputs the visual representation but the main output window gives a Warning. I have tried multiple syntax variations with no success.

Suggestions to retrieve the measurment appreciated.

In general, your schematic is required.
Just to verify your .meas statement and no problem was found.
