Multiple Measures Causing Circular Dependency

I have the following measures & columns:

Measures:

PYTD Hours = CALCULATE(sum(Table[Hours]), DATESBETWEEN([Date], 5/31/2017, NOW()))

MTD Hours = TOTALMTD(sum(Table[Hours]),[Date])

Columns:

MTD Variance Group =
if(Table[MTD Hours] > 100, ">20%",
if(Table[MTD Hours] >50,"10-20%",
if(Table[MTD Hours] > 20,"5-10%",
if(Table[MTD Hours] > 10, "0-5%",""))))

PYTD Variance Group =
if(Table[PYTD Hours] > 100, ">20%",
if(Table[PYTD Hours] >50,"10-20%",
if(Table[PYTD Hours] > 20,"5-10%",
if(Table[PYTD Hours] > 10, "0-5%",""))))

MTD Variance Group works, however I keep getting an error on PYTD Variance Group:

A circular dependency was detected: Table[PYTD Variance Group], Table[MTD Variance Group], Table[PYTD Variance Group]

Thoughts?
