Cannot select nor delete a graphic.

Hello,

I am beginner with FM. I am working on an existing catalogue. I cannot delete or select any of these 4 labels you can see on the page (google drive link) and I need to replace them by the french version.

There are not in an anchored frame or on a master page. Really I have no clue, so far I have been putting the french label on top, but sometime it is hard to align to avoid seing an overlap, so it's not the best.

Google did not help.

Can someone see what is the problem and how it can be solved?

here is the link for the page: https://drive.google.com/file/d/0B__STOrOSo8ERGpuaHZfbkg4OFU/edit?usp=sharing

Thanks a lot for your help.
