Accidentally left out liability order from application

I recently completed my undergraduate degree in a UK university and recently applied for a student visa for my postgraduate course (outside the UK).

During my studies, I was accidentally charged council tax despite being exempt, and a liability order was granted against me, however this was cleared up after contacting the City Council.

In the visa application when asked whether I’ve had any civil court judgements against me, I mistakenly interpreted this as a question about CCJs and so I said no (since a liability order isn’t a CCJ).

Would this count against me in the application? Should I reach out to UKVI to correct it or would this require the application to be withdrawn and a new one submitted?

It seems unlikely to need any action, but best check with the international student adviser at your university whether there is anything you need to do.
