Failing to comply with vehicle restriction Douglas road Redbridge 53j

I received a 53j contravention. But i do not understand as the school that his refers to is not in this road. The school is behind the road, with no access from Douglas road.please look at the images

It seems ridiculous that this road has no association whatsoever with the school they state the restriction it is for. I s there a legal distance or defined location for these restrictions.

For meaningful advice please to have a read of

and post here all sides of the PCN, redacting only yr name & address,
and a GSV link to the location.

It's simple; surrounding streets are also restricted to stop parents with children at the school parking there.
