Can’t change number concurrent streams

[townsmcp]

This app is fantastic. The only issue is the concurrent streams. I have 3 streams from my provider however when I set concurrent streams to 3 and tuner type to use as IPTV, it keeps going back to 2 streams.
I have a Technomate TM Twin 4K (which has 2 tuners inside) box with OpenATV 6.4 installed, on Grogbuild.
On About for HR Tuner Proxy it shows the following (installed from Plugins)

I use Jedi Maker to pull down the XC code and populate bouquets.

If I set tuner type in HR Tuner to ‘multi’ I understand Tuner Count is 2 due to the number of tuners in the box however if I set tuner type to use to IPTV and set numbers of concurrent streams to 3 (or even 4) and set the bouquet to use to a pure IPTV bouquet, after the box reboots tuner count/ concurrent streams always goes back to 2 - the value I set is ignored. When add the tuner to Plex it only shows 2 tuners.

How do I force the number of concurrent streams to more than 2?
