Multi-language term-bases

I am having problems with a multi-language term-base using Multiterm 2014. I started off by creating a term-base from scratch including all of the language that I needed in the term-base. However, once imported, I was unable to see the languages listed (I couldn't seem to get to the display where English terms were on the left and the translated terms were on the right hand side, in list/flag format). So, I started the termbase again using a converted glossary excel file where I had added all the languages I had and also left some free columns with headings for additional languages when I want to add them later. This worked beautifully. I was able to display all terms as I had expected. I then imported an additional language (which I had included in the language field), and the terms have been imported into the termbase however they are not visible with the other languages. I can see that the terms have been imported and can select those terms as the 'base' (left hand column), but there are no matching terms, and when I have English as the base language this a language does not show up with all of the other languages that were added in the original glossary. I'm totally lost!!
