Purple lines on maps after update

[FrankAS]

I apologise if this is a very simple matter. I have just updated the map for my region (on a Moto G6 Plus phone), and now there a purple lines all over the place perhaps marking bicycle routes (which I have not seen before, and that do not interest me as I walk rather than cycle). I have not been planning or altering a route. Please can someone tell me how to get rid of these purple lines? Thank you.

These may be settings in the map theme. There under Layers.
