Steam Signal Sb4623 At Aston Not Clearing Following Latest Update

After tinkering about with mods, it looks like the 'Adjusted Signal Approach Release From Red' mod causes a major bug with signal SB4623 at Aston on the Cross-City Line where it will not clear under any circumstances. Just thought I'd mention this in case anyone has encountered the same problem.

Pity as it's a very useful mod and which worked fine in TSW3, 4 and 5.
