Traffic violation ticket payment

We were in town the other day, and turned right at a junction after checking the road was clear. We were then flagged down by the local police and had to produce all documents etc. My hubby received a traffic violation ticket, for not stopping at the junction, even though it is a very wide junction and visibility of incoming traffic is 100%. As said police officer was writing out the ticket, all other road users were doing exactly the same thing for which we were stopped for🤷. Anyway, we were told we could pay at an Easypay office or online. As we were in the vicinity of an Easypay office, we proceeded there, only to be informed that it wasn't in the system yet. We have since attempted to pay online via Epay and through the interior ministry's website, without success. After inputting the requisite info, we receive a message back saying "According to the specified verification criteria, there is no data on unpaid obligations under a ticket, criminal decree or agreement related to administrative-criminal activity, stored in the AIS of the Ministry of the Interior, or there is no correspondence between the data in the criteria you set."

Is there something I'm doing wrong? This happened Thursday, so would assume that it had been registered in the system by now?

If all else fails, a further trip into town looks likely as only a grace period of 7 days is given.
