fill command not replacing when filtering for leaves

I need to change a large amount of blocks in a map I'm working on and tried using the fill command to filter for some of the leaf types and replace them with some of the wool colors.
I'm using a WIP resource pack, but I haven't changed the leaves (the block that seems to not be filterable)

I wasn't sure what went wrong because there was no error message, so I tried a few variations with a small area.

This is what didn't work:
/fill -467 91 -461 -466 91 -457 wool 13 replace leaves 3

This did work:
/fill -467 91 -461 -466 91 -457 wool 13 replace wool 14

I also tried the command with leaves 0, leaves 1 ... leaves 7 with no success and no errors.
