Why are these markings 'traffic signs'?
Section 64(1) of the Road Traffic Regulation Act 1984 (https://www.legislation.gov.uk/ukpga/1984/27/section/64):
(1)In this Act “traffic sign” means any object or device (whether fixed or portable) for conveying, to traffic on roads or any specified class of traffic, warnings, information, requirements, restrictions or prohibitions of any description—(a)specified by regulations made by the relevant authority, or
(b)authorised by the relevant authority,
and any line or mark on a road for so conveying such warnings, information, requirements, restrictions or prohibitions.
The back of the ticket has an 0845 number, which is relevant based on Paul Bateman v Derbyshire County Council (DJ00037-2209, 10 November 2022) (https://drive.google.com/uc?id=11TEzgfHFInCTo-JTFFtWJ8pbIXnMvJCd).

I can’t imagine anyone else taking the time and expense to mark out parking spaces, but if they deny responsibility I wonder whether they have the responsibility for markings made by others on their highways.
It is possible local businesses might have done so, but they've been marked for a lot longer than a year, they're clearly visible in the GSV from 2008: https://maps.app.goo.gl/F37VdueMtg3LFzkK6
LATOR 18 (https://www.legislation.gov.uk/uksi/1996/2489/regulation/18) says (my bold):
Traffic signs
18.—(1) Where an order relating to any road has been made, the order making authority shall take such steps as are necessary to secure—
(a) before the order comes into force, the placing on or near the road of such traffic signs in such positions as the order making authority may consider requisite for securing that adequate information as to the effect of the order is made available to persons using the road;
(b) the maintenance of such signs for so long as the order remains in force; and
(c) in a case where the order revokes, amends or alters the application of a previous order, the removal or replacement of existing traffic signs as the authority considers requisite to avoid confusion to road users by signs being left in the wrong positions.
Ergo the council was duty-bound to remove any ambiguous bay markings, whether officially sanctioned or not, to avoid confusion to road users. The council has defaulted on that duty, ergo the contravention did not occur.
