Apologies for my intermittent support on this (family issues at present).
I've checked the Saorview website for service interruptions and to verify the transmitter frequencies. Definitely C39 and C45. The fact that you are getting the lower channel 39 and no signal on 45 might indicate a cabling issue or possibly water in the cable. Also could be an unsuitable aerial, but unlikely unless you are on the fringes of reception of Spur Hill. Can you confirm that the Saorview website is telling you that Spur Hill is your ideal transmitter? The website has an address checker and it will give the bearing and distance of the transmitter from your address.
What is this bearing and distance? Are you sure your aerial is horizontal (the elements are flat and not pointing up and down)?
Other things I noticed in your setup. The channel numbers are not the actual numbers used by Saorview, so I suspect that you are not using "Alternative Numbering Mode". I use this as it simplifies things for me and other users in the house. Saorview starts with channel number 1 (RTE1), then channel 2(RTE2) and so on. The satellite channels for Sky start from 101.
Here is a screenshot of Alternative Numbering mode
Here is the Saorview list with the channels starting at 1
Here is the Sky list with the channels starting at 101 - ignore the fact that the Saorview channel 30 and the PoP cartoon channels are on 50 and 58 - these are a consequence of my combined bouquet settings.
I would also simplify the Sky ABM settings if I were you. You have all the sections bouquets enabled. I have only the main bouquet enabled which means it doesn't generate a separate listing for each section.
Finally - this is my list when I press the BLUE (Favourites) button in the channels list (press UP arrow or DOWN arrow first). Note that I have just one entry each for Saorview, Sky and Freesat. Again, ignore the multitude of IPTV lists - they are just testing placeholders for me.
Hope this helps in the configuration. You do seem to have some sort of signal/cabling issue, though.
