Not a complete translation of all text

Hi. I have used Transposh to do a partial human translation of some of my website. I then carried out a mechanical translation for the rest.

Problem: on a small percentage of the content has been mechanically translated and I can see no pattern as to why. The content is both standard wordpress pages and also Slider Pro but there is no apparent consistency.

I am using WP 3.5 multisite.

Thanks Kilotank
