For anyone else with this issue, according to Humax website, support, software area a new version of the software was created on Friday 19th
Unfortunately I am yet to download and find out if it has fixed the issue. As I only just happened to notice the "fix" by chance while at work just now. Ironically, a couple hours ago UK Humax Support messaged me and said... "At this time, we do not have a completed time frame for this". In reply to me messaging and asking when the fix would come!
Obviously communication is as good as their testing at Humax.
