Could it be they didn't sell a boundary ticket but a ticket from that
station instead and the fare is calculated differently?

They should be able to do it at Farringdon as they are used to NR fares but
it may take a bit of time looking at charts etc.

I occasionally travel from London to St Albans and back on a Saturday.
Having a Freedom Pass, I normally purchase in advance a Boundary Zone 6
to St Albans day return with a Senior Citizen Card discount which costs
£2.20.
A few weeks ago I needed to travel there at short notice when I was near
City Thameslink, but on Saturdays the ticket office there is not open.
Rather than travel through without a valid ticket I detrained at Elstree
& Borehamwood, the boundary station, to rebook and was charged £2.90. I
have never previously found a Boundary Zone 6 station where the actual
fares were different.
Does anyone know whether the LU office at Farringdon can issue Boundary
tickets with Senior discounts?
