See the attachment for a working configuration that exposes three different 
locations using different rules,
loc1, loc2 and loc3.

Using the following URLs, you can reproduce the erroneous behavior:

http://localhost:81/loc1?id=12&name=foo
http://localhost:81/loc2?id=12&name=foo
http://localhost:81/loc3?id=12&name=foo


TIA for your help!

Carsten

We would need to see your entire unmodified configuration file to help with 
this. Additionally, it is MUCH better to use a map directive for most cases 
where $arg_ARG is used.
