Trek problems

Hi, setup a trek for my trip to Tassie in the weeks leading up to the trip. I am at Geelong awaiting the ferry and decided on a change. Big mistake. Two frustrating hours later my trek is still not correct. I think the problem started when I lost internet for a few minutes. It made the spots I worked on direct and flights for some reason. Despite deleting, designating them driving etc cannot get rid of them. They appear baked in forever now. Interesting the flights go out over australia to the middle of the Indian ocean and then come back to Tasmania. Yeah a few bugs there I think or perhaps China has a new base they have built there.

The data on my trek info is incorrect in terms of the distances as it seems to finish the trek where these flights are even though the rest of the trek waypoints are visible. when I look at the list of places they are all there but the map doesn't agree with the directions. I have tried all the obvious things like restarting the app, rebooting the tablet but it continues . I tried selecting cycling for these flight legs but same result they remain visible even when the waypoint list is corrected. Next time you go in the list is incorrect again despite saving the list when it appeared correct.

I don't find the interface very intuitive and I found the app has quite a learning curve and building treks is a bit ponderous but I can live with all the quirks once I got use to them but not sure about this other behaviour. Unless somebody has a fix I might just have to revert to using the app as a tablet version of a paper map which is a bit disappointing.
