The sign is very close, almost right by your car, if I understand correctly where you parked. On the other hand, if the kerb blips were almost gone as it seems is the case, then you have been mislead by inadequate signage. Adequacy of signage is a duty on the council under Regulation 18 of The Local Authorities’ Traffic Orders (Procedure) (England and Wales) Regulations 1996
https://www.legislation.gov.uk/uksi/1996/2489/regulation/18So I suggest you submit representations based on this, and also point out you are a BB holder, and rely on clear sign indications when parking with your BB on yellow lines. Post up their response when you get it.
