Indeed, the new devices do treat things differently. My Nav V and VI operate very differently to my old Nav IV, 660 and earlier devices.
OP, try Berin’s suggestion of switching between version 1 and version 1.1. I looked at the MyRoute forum where some bod suggests that 1.1 sends more ‘stuff’ through. If the bod is right, it may well explain why you get the blue flags. Unfortunately, the increased ‘stuff’ is read by a modern Garmin device to mean that a simple shaping point (a blue dot) is a via point (a flag) and then displayed accordingly.
If the suggestion of switching between version 1 and version 1.1 works, then you have a solution. If it doesn’t, then try:
A. BaseCamp
Load BaseCamp onto your home computer.
Display the MyRoute route on it.
I am going from memory here and I use a Mac, but it’s something like..... ‘Route properties’ or ‘Get info’.... Highlight or select all the intermediate points (ie the points that are causing the flag problem) and change them into unannounced shaping points.
Send the route from your PC to your Garmin device.
Does that fix it?
B. Contact the MyRoute forum via their website. It is their software that is causing the problem, so they should hold the fix.
The simple truth is, if you can create a route in MyRoute, you can certainly create a route in BaseCamp. If you start to use BaseCamp, then the problem will go away. If nothing else, you’ll have removed the misfit between MyRoute and modern Garmin devices, caused by MyRoute. Why MyRoute do not fix the problem via an update, I have no idea. Instead, they rely on their users to fix it for themselves. Is Garmin perfect? No but they are pretty good at mending problems that appear. Sadly, the same does not apply to third party software providers, who proliferate on the net, coming and going with the regularity of the seasons. Their software might well be ‘biker friendly’ but sadly, like some bikers, they hide when there’s a problem to fix.
There are lots of users of MyRoute on this forum, many of them using modern Garmin devices. Logically, one or more of them will know the answer to your problem. Or maybe they all just live with it, as a trade off against not touching BaseCamp, as their mate has told them it’s shite?
Let us know how you get on, please. If you find an easy and reliable fix, tell us what it is; I’ll make it into a sticky.

PS I found this, which may help you with suggestion A, above:
https://support.garmin.com/en-GB/?faq=POYXggoD3p19jQOwZCvFA6 That shows the conversion of just one point but you have maybe hundreds. There will be a way to select multiple points and convert them all at once. The great thing is that you can’t break anything, so play about.
