Translation Feature doesn't work normally

There are more things in heaven and earth, Horatio,

Than are dreamt of in your philosophy.

To exlude that the XLIFF file was not completely or not correctly translated, you can open the translated XLIFF file in a simple text editor like Notepadd++ and scroll to the end. There you will find the translation units.

If the CAT tool the translator is using works correctly (or is configured correctly), than all <trans-units> should have a source element, the <seg-source> element with all the source language segments (<mrk> elements), and the <target> element with all the corresponding <mrk> elements with the translations.

It looks like this (simplified for better readability):

<trans-unit id= "1">
    <source>This is the first sentence. This is the second sentence.</source>
    <seg-source>
        <mrk mtype="seg" mid="1">This is the first sentence.</mrk>
        <mrk mtype="seg" mid="2">This is the second sentence.</mrk>
    </seg-source>
    <target>
        <mrk mtype="seg" mid="1">Это первое предложение.</mrk>
        <mrk mtype="seg" mid="2">Это второе предложение.</mrk>
    </target>
</trans-unit> 

Can you please check this and post a screenshot or te code from your translated XLIFF file?
