JET 2 SEAT SELECTION SHOWING BLUE🔵

[Eggybreadwithnuts]

So booking flights....picking my seats and one seat keeps showing blue....one point flashing blue. No matter what seat I select, one on return is blue. No way am I booking without a green seat allocation.
Ive rang and guy said oh Ive heard of this but not sure, wasnt much help

Anyone ever had this?

Anyone???

Google suggests it could be the extra legroom seats, which are also emergency exits so not suitable for DC.

How many of you are travelling? We fly jet2 a lot, never pay for seats and are always together even on full flights.

Nope no kids

Its just the lead passenger seat. Ive just checked in for our jet 2 flights a week tomorrow, and this happened.
