Filters sorting TO correctly but not FROM for day/month view

I'm using Calendar + Views to filter through shows, which each span a range of dates. Search options allow for content to be filtered by Year and Month, while a small calendar module on the home page allows for content to be filtered by Date. In both cases, the content will be filtered TO correctly but not FROM. So if I filter by Date, content will start at the correct date but also show content from all dates past that. Same goes for the Month view.

I've tried a variety of settings for the Filter Date node, but right now it is at:
>= FROM this month TO blank, exposed, day granularity, Content: Open to Close Date Range (field_open_date) - To date

If I do something like "is between," it filters correctly but I'm looking to show just the selected month or just the selected date. Any suggestions?

Thanks!

Here's what I have for the filters handler, if that helps:
