Pending Joblog invalid create date

Before I have someone talk to IBM, does anyone know how I can remove a
pending joblog with a create date of 08/23/1928 ?

The WRKJOBLOG display issue an "invalid date" error when trying to use opt
4 to delete the log.
The joblog server can't get past it, and we are accumulating pending
joblogs (over 100,000).
The job that created this log is QPASVRS
according to the text of the CPD0082 valid create dates are 8/24/28 to
5/09/2071

This sounds like there should be a way to alter that "window".
This is V7R1 and oldest pending joblog is from 2015.
Have ended and started joblogsvr and still same.
IPL quarterly..
Cume through 15142, but that was applied after oldest pending joblog.
We did not notice till active jobs got very high.
