Ouch... That humidity is quite high, but there's nothing you can do about it now.i am using this incubator https://www.amazon.co.uk/gp/product/B07NT11F94/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
and the humidity levels have been 55-65 throughout and then 65-70 since lockdown
now that you've mentioned this I think I would go ahead and candle each egg to make sure they're still moving around in there.
