PSRedit 500 Unsure of audioboost setting

[Dewman63]

I have a PSR600 scanner and I want to turn on audioboost for just one TYSC and all the talkgroups in that system. The help file for PSRedit500 version 1.88, release 1, build 194 says that going to the edit screen for the particular TYSC that I want and checking the box to turn audioboost on should turn it on for all talkgroups associated with that system. After making the change and downloading to the radio I manually checked in the radio and it was turned on for the TYSC but not for the talkgroups. Also in the software, there is a column after each talkgroup object that shows whether audioboost is on or off and it shows No. I could edit each talkgroup and turn it on that way but I was just wondering if this was a glitch in the software or I was not doing something right. Thanks for any help!
