No answer, so I try to help you....I notice the same bug. How did you fix it? Could you please tell how to get the config file and where to put it? I was running TS CM 13.1 before, too. Thx.
I think you can try to unzip TS CM13 zip and look for the gps.conf file in /system /etc .
Just erase yours and repalce qith this one. Need root of course....
Right should be RW-R-R
