I want people to select a date in July or August so I set 

minDate to July 1st

maxDate to August 31

numberOfMonths: 2

But when people select August 1st, July 1st becomes highlithed to. Like if it was mouseover.

The mouseover effect disappears when selecting another date in August or when I mouseover a date in July.

If setting the minDate to July 3, the bug appears when selecting August 3.

Any idea?

Thanks!
