Not in 1.7.10 version, but in 1.10.2 version, many machines are called different machines when using waila and walwa (which also causes the robit crash) Somebody is currently doing a 'survival with mekanism' series and also has the issue.

If you notice here, all the machines are called enrichment chamber etc. Do not have an extensive list of which machines are called what.

Known issue, sadly on WAILA's end.
