An annoying bug (well, I consider it one) is that if you have a season
ticket on Oyster, PLUS some pre-pay (for paying out-of-zone extensions
automatically), then the gate does NOT tell you when your season is due
to expire.

However, if you JUST have the season, then it does tell you "Tkt 1 Nr
Expiry" (or similar).

In the latter scenario, you know when your season ticket is due to
expire, and can buy a new one.

In the former scenario, it doesn't tell you the season is about to run
out, and eats away at your Pre-Pay without telling you until it runs out.

I've had a "Tkt 2 Nr Expiry" this week whilst I had both prepay and
season ticket so I don't seem to have the same problem as you
