Yeah, your fee estimations don't seem very accurate at all. At time of writing, your site is suggesting:
Fastest: 72 sat/byte
30 min: 66 sat/byte
60 min: 50 sat/byte
Looking at the third graph here (
https://jochen-hoenicke.de/queue/#1,2h), both 72 and 66 sat/byte put you with 0.5 megabytes of the tip, and so are both likely to be confirmed in the next block. 50 sat/byte puts you within 1 megabyte of the tip, and could also get you in the next block, but probably within 2 or 3 unless the mempool sees another spike in activity.
As OmegaStarScream says, bitcoinfees.earn.com is notoriously unreliable and grossly overestimates the required fees.
