Not getting the max expected value

Hello to all

I was creating the following calculated table:

Table 2 = 
ADDCOLUMNS (
SUMMARIZE ( 'Table A'; 'Table A'[issueid]; 'Table A'[Release] ; Table A'[LastRelease]);
"Last Date"; CALCULATE ( MAX ( 'Table A'[created] ) )
)

Where Table A is the one in the attached image.

The problem is that for issuedid 10544 I'm getting not the last value based on created but the one before that. 

In this case instead of getting 01/08/2017 15:54:01 I'm getting 01/08/2017 15:53:33 shich is not the last.

What am I doing wrong?

Thanks
