Solved: LSMeans Tests between Student's t vs. Tukey HSD

Has anyone seen this result where Student's t letters are the same while Tukey HSD letters are different. I usually see visa versa. Any thought?

I would not perform any post hoc tests until I validated the assumptions of the model and addressed all the issues with the estimation.

Did you notice the warnings in the report of the variance components?
Did you notice that your model is over-specified and the fixed and random effects are confounded?
Did you notice that one of the random effects is zeroed?
How do you justify treating gender as a random effect?

I don't think that this analysis is quite ready for any post hoc tests.
