This is not related with vBET.
I checked first links for no title tag and double title tags - see html yourself it is not true. Title tag exists and it is only one.
Duplicate meta is also not vBET issue - you have it duplicated in original content, so it is duplicated after translation (same sentence translated twice to same language will give you same result). So vBET is working fine in this area - your descriptions are translated as should be (just check it in page source). It is your part to give different content to translate.
Same to short meta - you have it short in original so translation is also short.
Please note that vBET is only translating your content it does NOT change it on any other way.
i have this problem too. i have almost 3000 duplicate meta and almost 2000 duplicate titletags. please for help?
