Missing colours and Google Home issue on Yeelight Lightstrip V2

Missing quite a range of colours:
Purple/ magenta ends up being this light blue or blue-white colour
Green ends up being blue-green like teal
Navy blue itself looks like blue-green as like teal as well
Even yellow is missing…
And setting up in Google Home is impossible. Have unlinked Yeelight from Google Accounts and reset device multiple times and repair and relogin to Xiaomi Account but still Google Home is telling me ‘this light is not set up’ and it doesn’t even appear under my devices/ main screen on Google Home… even though it says Yeelight is successfully linked.

Please help…
