Here on 27.0.50 the customize option for `find-ls-option` says

    For example, to use human-readable file sizes with GNU ls:
       ("-exec ls -ldh {} +" . "-ldh")

Is it ignorant to suggest to try this as a workaround? It "worked" here.
Thanks for this bug anyway because i have had the same issue sometimes
and I will continue use this option and see if it makes any problems.

Because ls doesn't seem to do this conversion -- inconsistent? :P
