RTE hyperlink AEM 6.4

Hi all

I have a problem with RTE hyperlink AEM 6.4

When the editor points a page in the hyperlink and after that comes back

the window opened isn't already set on the specific page (as it was in the 6.2 and  6.3)

You can see an example:

step 2

one difference I found is that version 6.3 of AEM

version 6.4 of AEM

I don't think this is the problem, but it's something different.

Thanks in advance and I wait for answers
