Change of note title not beeing saved on android

I often experience the following behaviour on android:
I open an existing note and make some changes on the title. The save icon becomes “white”, but I don’t click on it.
Then I assign this note to another notebook, say “mynotebook”. The save icon becomes “gray”, so I can’t save the note.
I go to “mynotebook” and there is the note. But it has the old title.
I know it isn’t really so important, I can save the note on the first step, but it seems to be bug.
