ANDROID Help with Igo Primo Average speed camera alerts

Hi,
I recently installed Igo Primo Multi 2.0 - 9.6.2.209584 from
The Best Igo Primo - Full Igo Primo Multi 2.0 - 9.6.2.209584 (thanks to JOYTURKX for posting it)
on my old Chinese 4.3" Windows CE sat nav. I then added UK Tom Tom maps and UK TTS voice. All is working well with only a few minor issues (long boot up time and reboots when exiting) but I have a problem with the average speed cameras. The regular speed camera warnings work well, before I added TTS I got quiet beeps when approaching and louder beeps when I need to slow down. When I added TTS it then also says a message which I am not bothered about. When I approach an average speed camera I get no audible warning, I see the icon on the map and sometimes I get an icon on the left showing my average speed. This additional icon also sometimes remains on the screen long after I have passed the zone. I would really like to have an audible warning when approaching the camera and a louder warning if I need to slow down, like I get with regular speed cameras.
I have done a lot of googling and reading about the sys.txt file and I am just getting more confused. It looks to me like they are set up correctly and should say "Caution average speed camera ahead"

[speedcam_category:3]
activated_spoken_type=speech
activated_speech="Caution average speed camera ahead"
;overspeed_spoken_type=1
warn_distances="150:2000,140:1800,130:1500,120:1400,110:1300,100:1200,90:1100,80:1000,60:700,50:600,40:500"

Any help fixing this would be greatly appreciated

Cheers
JD
