Previous YEAR vs Selected Year

Hi guys,

Please help with this DAX

I need show the value by select YEAR vs PREVIOUS YEAR

I am using this expression:

Max Year = CALCULATE(SUM(MyTable[REAL]); FILTER ('TIMEDIM'; TIMEDIM[YEAR]=MAX(TIMEDIM[YEAR]) ) ) 

this return Real value of year

and 

Previous Year = CALCULATE(SUM(MyTable[REAL]); PREVIOUSYEAR('TIMEDIM'[DATE]))

However when I put this measures in my table i have a repeat of previous year for all months

Like this

I have date from:

 Year 2016                             2015

Month                                  Month

apr  10

jun   5                                 7

jul    4

However when i show in table i have all months with value 7

YEAR actual                           Previous

jan                                          7

feb                                          7

mar                                         7

apr 10                                     7
