Mailspring not offered as choice on setting Win10 Email default app

Using the latest version on Mailspring. It is set in Preferences as Use as Default Email. I am then asked to go to the computer Settings/Default Apps. Email shows Mail icon. I click on Email and drop-downs list:
Mail
Chrome
Edge
Update.exe (Mailspring icon)
Windows Store
Is Update.exe correct or is Mailspring just not listed?
Thanks

Please disregard. I removed Update.exe as the choice and went to MAIL. Went back in and there was Mailspring!! OK, fine!
Fixed.
