Brief description of the error:

I am translating multiple pptx presentations and just by chance (I viewed a preview of the file being translated and glanced through a few slides in the presentation) I noticed that certain lines were not translated on slides which I had already finished translating.

When I compared the text on the slide in the pptx to the texts open in the Studio editor, I noticed that all texts from the slide were available in the editor for translating except for the 1 single line that was not translated. I was puzzled as to why it did not appear in the editor in Studio, but I also have no idea what to do about it. It is also concerning if Studio cannot be relied on to make 100% of the text in the pptx file available for translation in the Studio editor. But I don't know if this is a Studio error or an error in the pptx.

But I have now encountered a new instance of this problem; again by chance I noticed in the preview of a different pptx file that a sentence in the pptx was not in the editor, so it remained untranslated in the pptx file.

Both sentences in question are simply situated within paragraphs of other text on the respective slides, and I cannot see any special reason why they would not have been "noticed" by trados when the files were added to the project and made into sdlxliffs.

So what does one do about it? I am right in the middle of a big translation project and don't have time right now to spend on examining this question, but I am stumped as to why it is happening and what the solution is.
