Kind of the same issue going on for me but using symantec altiris, I build my image using MDT, installed edge, went through and set it has the default browser, even went ext by ext and anything that was old edge I set to the new edge. Sysprep and grab the image, deploy
New edge is set as the default mail app but old edge is showing the main browser, click on the main browser option and the only options are new chrome or IE, look at file ext and they are all set to old edge. Guessing this is due to the aggressive level they built old edge to be the default browser in win 10. Even when we set IE 11 using dism in the MDT creation when a fresh image would deploy you get pops up saying "default app had an issue setting it to edge" yet IE 11 would still be the set to to main browser
