SQL error if date field set to multiple values

Hi.

I'm filtering a view making use of the daterange.module. The filter is defined as:
Custom date range: between 'today' and 'today+100'

I've tried to change the filtered date field to have multiple values, but then I get the following error instead of having the right view:
