Grafana + timescale db not showing all entries for expression

Hey,
im currently using timescaledb + grafana, and it works wonderful so far,
the only bad part is that the query builder does not display all entries in the where expression.

It should show around 400-500 rows, however, it displays only around 20.

What happens if you scroll down the list?

Also, if you start typing, then the list should be filtered. That might help get you where you need to be.
