Resolution

Workaround 1:

1. Open the *.sdlxliff in Trados Studio - Editor View
2. While in Trados Studio, go to File - Advanced Save - Save Source File As
3. Reopen the newly saved file in Trados Studio

Workaround 2:

In Trados Studio, scroll slowly through the *.sdlxliff and search for where the the misalignment between source and target starts. That is where the issue is located.
Open the *.sdlxliff in a text editor and search for the text in that particular segment.
Review the segmentation and identify where is the missing segment. In this situation, the source and target looked like the example below. Notice that the source contains two segments and the target only one. To fix this file, manually add the second segment in the target.
NOTE: Use an advanced text editor, for example Notepad++, and use the Pretty Print function so you can easily identify tag pairs; otherwise it would be very hard to identify the problem.

Source:

<seg-source>
<g id="988">
    <mrk mtype="seg" mid="346">Lyr.</mrk>
    <mrk mtype="seg" mid="347">
    <mrk mtype="x-sdl-location" mid="648899f5-f4d5-4eac-a7c5-1c05df82a3c8"/>Arise, children of the Fatherland, the day of glory has arrived!</mrk>
    <mrk mtype="x-sdl-location" mid="0f8471b1-068b-4630-9bee-e5e332b51728"/>
</g>
</seg-source>

Broken target:

<target>
<g id="988">
    <mrk mtype="seg" mid="346">Allons enfants de la Patrie, le jour de gloire est arrivé!</mrk>
</g>
</target>

Fixed target:

<target>
<g id="988">
    <mrk mtype="seg" mid="346">Lyr.</mrk>
    <mrk mtype="seg" mid="347">Allons enfants de la Patrie, le jour de gloire est arrivé!</mrk>
</g>
</target>

Root Cause

This may happen when during a merging operation one of the target segments was not inserted correctly in the *.sdlxliff. It may also be useful to check the source file for irregularities.
