The Minexbank has wrong parking rates since the last release (I think one or two months now). It will only apply 10 percent of the actual rate that has been chosen.

For example, choose 6 months - 20% and it will actually use 2.0000%.

Is this a known issue?

-- Update --

Found it: https://minexbank.com/memorandum.

This is totally not clear when you're just using the MinexBank and haven't read the memorandum.
