I am trying to modify the Categories MetaTags using ZC 1.50 and EP4.0.19 - Beta 1-28-2012. I downloaded the file, CategoryMeta-EP2013Jan28-114334.csv, sorted it, and then added in MetaTags and uploaded and imported back in and got all my categories and subcategories recreated at a top level. No tags were entered. So if I had originally:

Category A
---->Brand A
--------->Model A
--------->Model C
---->Brand B
--------->Model B

I ended up with the following structure:

Brand A
Brand B
Category A
---->Brand A
--------->Model A
--------->Model C
---->Brand B
--------->Model B
Model A
Model B
Model C

I ended up having to go in a deleting these new "extra" categories (which were empty). Any idea what I might have done wrong? I uploaded the same file name as I downloaded, as I know this is important to getting it to work properly. I recall getting this to work at one point and the regular product upload function works flawlessly.

Thanks!
Brian
