The GPX file produced by MyDrive is not compatible with OS Maps (1:25000and 1:50000)

Hi, I use MyDrive to plan my routes on my MacBook. I want to export the planned route to OS Maps on my IPad. I have exported the GPX file to my desktop and synced to my iPad using Bluetooth. This has worked in the past giving me the planned route highlighted on the offline OS maps. With the gps activated on the iPad my current position is shown. The last time I tried this the full route was not imported correctly and OS maps says there is a problem with the GPX file format provided by MyDrive. I am still waiting for OS Maps to tell me what is wrong with the file format. Do I need to run the TomTom GPX file through some software to clean it up? Anyone got any ideas please?
