Subscription Analytics / Usage Details - Filter questions

Subscription Analytics Services / Usage Details - Filter questions,

I'm sure this is still a WIP site, I just wanted to ask a couple of question regarding the usage of the site

When trying to filter on a product and a date range, you can select one or the other, however the second filter removes the first, I can filter on date range or product but not both, so for instances I cannot search for MicroStation usage last week?

Also why do some filter options in the drop down menu have a grey background is this significant?

Im sure there may be more questions once I look further

Cheers

Chris
