! task 1 failed - "number of levels of each grouping factor must be < number of observations (problems: ID)"

When I try to use the mStat_generate_report_long() or generate_taxa_per_time_test_long() I get the error, "! task 1 failed - "number of levels of each grouping factor must be < number of observations (problems: ID)"". For my analysis my grouping variable is called "group" and has two values, "disease" or "control" and my subject variable is "ID". I have no issue running, generate_taxa_indiv_boxplot_long(). Please let me know if there is anything I can do to get these functions to work.
