Just to humour you.. I'm new here but stumbled on the thread and thought I'd add my experience. Pic is after selecting to send the entire balance. As you can see the fees are crazy. Not shilling.

Also have similar behaviour (Electrum)

The wallet has 0.0215, and if I use the auto-calculated fees to transfer it all, the middle fee selection (default, within 5 blocks, 357 sat/byte) is ~0.0107, and the low (within 25 blocks, 253 sat/byte) is ~0.0076, both are crazy. I hodl anyway, but I guess my coins aren't moving. I used to use faucets, so I'm guessing that's made things a bit of a mess.
