Hello Huw,
what happens when you remove the period '.' in the residue range description,
i.e., replace
RANGE 'B 3.' 'B 3.' P
with
RANGE 'B 3' 'B 3' P
?

However when I divide a single nucleotide into 3 TLS groups only the first group has its origin calculated and actually has TLS parameters refined:
