warning message on second submission

The attached problem runs fine the first time I submit an answer. If I submit a second time, a warning appears. This behavior does not occur on the webwork server I am running in my office (version 2.13 webwork2 and pg), but it does when running on the MAA server as:
$BR https://courses1.webwork.maa.org/webwork2/Washington-Math307C/instructor/pgProblemEditor3/M307-duchamp-test-set-1/10$BR\$BR
The 3 tests, one of which is causing the error, are on line 160 of this file.
The warning message refers to "[PG]/lib/Value/AnswerChecker.pm line 252". I have looked at that file but can't
understand well enough to guess why this is happening.
I don't know how to determine the version running on the MAA server. Any advice would be greatly appreciated.

thanks
John

You have line 103

Context()->normalStrings;

commented out. If you uncomment that line, the error doesn't occur.
