Your best bet is likely to upload a copy of the .fzpz file for your new part here (upload button is 7th from the left on the tool bar in reply) so we can look at it and comment. Late versions of Illustrator (I use Inkscape so don't know the version) have had a change in translate format that Fritzing can't process which makes things move incorrectly (don't know if that's the problem here). In Inkscape there is an xml editor window and you can see if the silkscreen tag is still in the svg. Note if you change the svg file you do need to recreate the fzpz file (I usually use 7zip to do that), if you don't the original svg will be still there and that too may be your problem.
If you upload the fzpz one or more of us will have a look and comment.
