Ghost vertex while modelling

Can anyone please explain why I’m getting the following anomaly when viewing in Object and Edit modes? I’d like to know if this is a common occurence and if there’s anything that fixes it easily before I delete that entire section and remodel :(.

maybe you have hidden that part in edit mode. Try pressing ‘alt + h’ while in edit mode to revel hidden verrtices.

Ah yes! That was it. Thank you so much. I must have hidden it by mistake.

Sorry, didn’t even think that you could hide “things” in edit mode. I thought hiding was only in object mode.
