Unfortunately Lacerte still uses Internet Explorer for many of it's features. You probably need to update your IE, even though you have EDGE.

From Microsoft:

Microsoft Edge is designed for faster, safer browsing and is recommended for Windows 10.

But Internet Explorer 11 is also included in Windows 10 and is automatically kept up to date. To open Internet Explorer, select the Start  button, type Internet Explorer, and then select the top search result.

To be sure you have the latest version of Internet Explorer 11, select the Start  button, select Settings  > Update & security > Windows Update, and then select Check for updates.
