Route directions advising to turn off/back on planned route

[Skellum]

I travelled back from a tour in Wales last weekend and experienced some odd route instructions during my ride whilst using the latest update and CarPlay to a Chigee screen, these included showing and advising me to turn into cut-de-sacs and then back out again. This happened at least 5 or 6 times, When I got home I checked both the app on my iphone and MRA planning app on the net where I had devised the route, neither showed these diversions from the main route. All of the route errors were made on small back roads so I am guessing it must be a 'Here' issue rather than the app? The only other issue I had on that trip was very unusual, upon arriving at a roundabout it advised me to take the 5th exit, but the round about only had 3 exits, I then realised that it was asking me to go around the roundabout once and then take the 2nd exit (so total of 5) which was actually the route! Once again I have assumed it to be a 'Here" issue rather than the app.
