You were probably in a two hour non-resident zone, they'll have proof that you were there two hours prior to the first ticket and the next ticket was because you didn't move for at least another two hours.

You might be able to plead it down to one ticket with the prosecutor, but that doesn't seem worth the hassle to me, even if it is a zoom call.

It sucks, it was probably an easy second ticket to issue, but if this wasn't enforced the whole city would become a park and ride for Manhattan.
