"Between" filter for numerical fields


I’m trying to use Between filter for an Int field on a list page. When Between is selected as filter operator, only a single text box appears and there’s no clue on how to specify start and end values.

I have already tried 5,10 , 5 AND 10, (5 , 10), (5 AND 10), 5:10, etc but it gives below error.

Any tips here? Or is it a bug?
