I've been asked to extend the "Time Windows Matrix Report" in Field Service Lightening to 45 days out.  Can somebody dumb this down for  me?

This report includes "Start Date" and "Time Window Number".  I've been trying to figure out how to set the "Time Window Number" (I think) for DAYS.

Can anybody shed some light on this?
 

Thank you 
 

I need to remove the Standard Record Type Field from Library Page Layout. I had record types earlier which I have deactivated and even deleted but still the Master Record Type is present on the page layout of Content/Library when we try to contribute a file.

Methods I have tried :

I have deleted the Record Types. Still the field is available.
I have deactivated the record type. Still I was able to find that field.
I even tried to remove the record type access to the profile. Still the field was there.
