Looks like it.
So OP, you were parked across the dropped kerbs with the wobbly paving stones, and just so you don't miss them, the council or somebody has painted the dropped kerb white. The contravention would therefore seem to be made out.
There may be a technical appeal argument based on the council management of the enforcement process and maybe PCN content, although the PCN looks OK to me. SO wait for others to comment but don't miss any deadlines on the PCN that may restrict your payment or appeal options.
