There is ample evidence to show that L9027 was still in RAF service long after Jan 40.
It served with 57 Sqn for much of 1940. To save downloading copious ORBs, see how many times it appears "on the roster" here:

Hopefully someone can provide a copy of the Form 78 for both L9026 and L9027 which will solve the matter once and for all.
