Red recording dot in guide missing

Hi.
Firstly, loving the new Krypton interface!
I am using Kodi Krypton 1.72 beta from the Windows store and Next PVR 3.7.7. Tuner is a wintv dual HD USB by Hauppage.
I have noticed the red dot next to programme text on guide to indicate a show us being recorded doesn’t appear when recording on one tuner. If I record two at once, then the second programme will indicate the red dot, but first one won’t. This makes it hard to notice if tuners are recording or not especially since trying to play a 3rd instance when 2tuners are working crashes the PC. Can you fix this lack of red dot and a warning message that all tuners are in use to prevent crashes?
Let me know if there’s any tweaks I can do.
Thanks for your help.
