Hi Masoud Moghaddam

That's quite normal. The TMs you add to your project don't automatically appear in the Translation Memories pane. If you want to open one then you need to navigate to it via 'Open' as below:

If every TM created were automatically listed in the Translation Memories view it would get rather crowded very quickly. Also, the only reasons to have them in the list is if you wish to work on them, export them, import to them, etc. They're not listed just so you can see what TMs you have.

Another thing to note is that if you move a TM to a different folder after opening it in the Translation Memories view, it will disappear from the above list. Also, you can manually remove a TM from the list once you have finished working on it via 'right-click>Remove...'

I hope this helps...

All the best,

Alison
