Acronis TI 2014 is ignoring my exclusion list

Hi,
I recently upgraded to 2014 from 2012.
I am Running win7 x64.
Acronis automatically recognized by backup scheme.
It's a differential one with exclusions.
It created the first (full) back up which was ~60GB and from its size i understood that it was following my exclusion list. (mainly the picture folder)
However, when it came to add a differential backup it tried to create very large files - larger than 250GB and from this i concluded that it ignored my exclusion list.
I tried resetting the backup options and re-add the exclusions but it did not help.

In 2012 version all was working well.

Any kind of help would be appreciated here.
