Traveled line displays Black not Coloured

Hi my connect app is displaying my traveled route line as black, not coloured displaying different areas of pace, heart rate etc. I've changed lots of different things, deleted and reinstalled, cleared cache, disconnected and readded 3rd party apps. I think I've even gone into settings I don't think I'll ever find again ticking boxes trying to get the coloured line back. Also tried WiFi, vpn's and cellular network in different combinations to see if it was a data issue¿ No luck with anything. Is anyone aware of an app bug causing this?
