Forester1,
I, too, am having the same errors show on these. I have reverted <kuid2:209857:102:7> LIB | R51 Signal Kit | Mesh - Signal Parts (Modern) to version :6 but like you, that didn't fix things.
now have the following faulty signals...
<kuid2:209857:71105:7> NSW SL | 2a H | G
<kuid2:209857:71177:7> NSW SL | 1a M 2r Tu Sh | G
<kuid2:209857:71152:5> NSW SL | 3a H 2r Tu Sh | G
<kuid2:209857:71184:6> NSW SL | 2a H 2r Sh | G
<kuid2:209857:71146:5> NSW SL | 3a H LD Tu Sh | G
<kuid2:209857:71138:4> NSW SL | 3a H 2r Sh | G
<kuid2:209857:71149:5> NSW SL | 3a H RD Tu Sh | G
<kuid2:209857:71135:6> NSW SL | 3a H Sh | G
<kuid2:209857:71125:5> NSW SL | 3a H | G
which appear to be from NSW Donnybrook Branch and Illawarra South Coast NSW Australia.
I will try to back version these too, but then my list of obsoletes will grow even longer. (Its bad enough that there are "obsoletes" caused by the Mobile app without these too)
