a display Issues in under larger scaling settings

[gaosher]

hey,
thanks for your effort for developing this awsome app! in the process of using word-of-the-day, i found a adaptive display bugs under largest font size and largest display size.
Screen shots:

the back icon is overlapping with the text "Words learnt" in WordHistoryActivity.

app version: 2.0
device: Pixel 2
Android version: 10.0
screen resolution: 1920 * 1080
