In my system, decimal separator is comma. In transaction list in a GUI for all mounts decimal separator is point. But in amount filter field I can't enter point, only comma (which is decimal separator in my system), and, most likely because of that, filtering by amount does not work.

It's bitcoin-qt v0.16.0 with qt 5.9.4 on Gentoo Linux.
