Tags are not properly exported when exporting to SDLXLIFF

Hello all,

I'm am doing some tests with a .properties file which contains some embedded HTML. However, I'm facing the following situation:

I have the file in French as source language, I create my project in Passolo so I can align it with a previous version which is already translated. The HTML tags seem to be properly protected:

  

 

I would like to complete the missing translations through Studio 2017, however when I export the file to SDLXLIFF and I create my project in Studio with them, the tags of the first screenshot are still protected and displayed as tags, but the ones if the second screenshot (HTML) are displayed as plain text. How can I make them to be displayed also as tags? The HTML tags in the menu item Inline Patters is active.

Could anybody give some advice?
