Referring back to your track diagram in the original post #1, have you tried either R8073 point on its own to see if it works properly? It may be a faulty connection under the point?
Secondly I would put insulating fish plates (Hornby R920) at the joints where each pair of points joins together to ensure the two electrical feeds are kept clearly separate from each other. To cross a train over either crossover you will need to use both controllers on a similar setting.
I'd also agree with Pappa.B that the feed should be to the left of the two crossovers.
I don't know what period you are modelling, but for the last 3 or 4 decades two separate crossovers have been preferred to a scissors crossing - cheaper to install and maintain, but just needs a bit more space.
