Hii. i have a multi languages site on 4.7.1.1

I am try to make macro chching by changing the Chche Period from 0,
Chche By Page is set to true.

What i get is that sometimes the caching macro from site1 is showing on site2. / or macro from site 2 showing on site 1

When i check this with the debuge+trace i see that the name of the macro is good -
Macroname-currentPageId

This is the structure:

-Site settings ( lang 1 , hostname : domain.com)
--- Home page
--- About
--- More pages 
-Site settings ( lang 2 , hostname : lang2.domain.com)
--- Home page
--- About
--- More pages

Any idea will be great,
Thanks in advance.
