Adobe DC Pro on Windows 10 with HP Printer using twain scanner driver not showing custom scan option

Hello

I have been using Adobe Professional for several years and have been able to use custom scanning.  For several months I have not been able to do this.  I downloaded the twain driver for my printer HP color laser jet pro MFP M281dfw today and tried using that.  Prior to this, I only had the WIA printer driver and it would only scan using the printer interface--I didn't like this option so I started using HP Scan tool since then.

When I try to start scanning, I click on File, Create, PDF from Scanner and select the Twain scanner, but the Custom scan option is not available. Also--it shows that I am in the Enhance Scan Tool

When I click on the Create tool and try to scan from there, I click Scanner and select the Twain driver, but the custom scan option is not available either.

There is a My Custom Settings option on both paths, but when you click the gear icon you cannot change the color mode, resolution or paper size.  The scanner will not scan from that point--it says Please input some valid page dimensions.

Please someone help me.  I have been using the HP Scan tool since this stopped working--but I do not have the control over the scan that I had when I scanned directly through adobe as far as being able to make the file size smaller.  

Thank you in advance for your assistance.
