Gtranslator doesn't show the words I want to translate.

I use gtranslator to translate po files.
Gtranslator worked fine on 11.3 but when I installed 11.4 it crashed. I opened a Bug report here.

Although I followed instructions, I couldn’t solve it.

Now I use Gnome 3. I installed gtranslator from the page where it says about Gnome 3. Now my gtranslator is 2.90.

The numbers you see below are the words.
I don’t see a thing.
I can move to next word but I still cannot see anything.
Do I miss somethng? How do I fix tha problem?

I fixed it. I deleted the directory
