I'm not sure if this should be listed in the bug list or is actually a problem with my workflow.  I've had a series of problems with this timelapse that required me to use your guide to resetting the program in LRTimelapse.  Previously it was referencing "phantom key frames" that were no longer part of the project.  Resetting the metadata, and removing the old folder from the reference in Lightroom corrected the phantom keyframe problem.  The problem is now, when I attempt to use deflicker I get an error message that says "Can not calcluate deflicker curve values, try a different value".  Only I can not move the deflicker slider without this message popping up.  Any idea as to what is causing this error?

Try to reset all settings by right clicking on the folder and "Clear all LRTimelapse editing". Then start over, this should fix the problem.
