It seems that upon importing the file to OmegaT its content simply disappears.
The "import" function in OmegaT is a lazy man's way of copying the file to the /source/ folder. If you copy the file to the /source/ folder, and then use the "import" function, then OmegaT will overwrite what you've copied with what you "import". You seem to already know how to copy files to the /source/ folder yourself (some users don't know how to do that!), so you don't have to use the "import" function.
Try copying the file (make sure it is not empty) and then press F5 in OmegaT, and don't use the "import" function.
If the file is still not recognised, then maybe OmegaT does not recognise the file extension. Go to Options > File Filters and make sure the file extension listed there is the same as your text file's. You may also want to ensure that the encoding is correct (on the same dialog).
If the file you're copying is still open in the text editor, try closing the text editor first -- some programs lock files when they are open in them so that other programs can't access them.
The question is that I have a common source file folder for all the languages pairs, it's much easier than copying the same file in every different "Source" folder. Nevertheless, this is a strange bug because I've been doing like this for months and that didn't happen before.
As for compatibility, I use *.txt and *.odt files, so that should not be the problem.
