MAX measure not correct?

[Shure846]

Hi - I've got a table with USDA prices in it, and I'm using MIN, MAX and STDEV to give me an idea of how a commodity is tracking. The table has 4 different commodities in it, and MAX works for 3 of them, but not the 4th and I cannot figure out why. It's the same table being analyzed. 

The measure is : 

Maximum beef & pork = MAX('Combined beef & pork trim'[Weighted average])

Any suggestions?

I found out the issue - there were duplicate dates in the table. Apparently that confuses the DAX measure.

Can you provide sample data and expected result. At least screenshots would be a good start.
