Language copy for double language

Hi Team,

When we are trying to create language copy for a particular folder (/content/test) then for the double language only one subfolder from /content/test is getting created where as for the single language all the pages under the /content/test is created.

Example :

We have three folders under /content/test named as /content/test/testPage1, /content/test/testPage2 and /content/test/testPage3 when we try to select double language in the create language option i.e: ar_ae only /content/test/testPage1 is created where as when I try to select single language in the create language option i.e: ar all the three folder are created

Does anyone faced this issue?
