As seen in this image, the duplicate entries for Blacksmithing and Engineering claiming "MAX" concentration are incorrect; the entries with timers are accurate. Two entries present for tailoring, they are coincidentally both correct at the moment, though I'm sure one will be incorrect once I spend Conc.

FWIW I deleted my savedvariables to remediate other issues in CraftSim, and this issue went away as well. Could be I had some junk my my savedV.
