From your screen shots:
In Station settings I would untick Calculate dew point and wind chill as the Davis does this pretty well (the Cumulus option is mostly for some other weather stations that don't do this). I would tick VP 1-min barometer update and that will replace the Davis default. I would also tick Stop 2nd instance so that you would not in error start a 2nd instance of Cumulus running.
In Internet settings I have learned that it is best not to have the uploads at the same interval so I have PWS, WB, CWOP, WOW at 7, 8, 9, 11 min, and WU at 5 min but I use the Rapid Fire, and the Realtime interval at 5 sec.
You may have changed these but in the screen shots PWS and WU you have ticked UV but the Davis Vue does not have UV.
When you are ready for uploading to your own website
some more settings to do.
The following is the Davis datalogger time period and this is were you should have the WL datalogger and Cumulus data log interval settings the same:
