Ok, so no. Yours is a completely different issue. The file names are correct, but you are concerned about the actual tracks displayed.
This is actually Windows Explorer being stupid about reading the tags from the files. In this case it is displaying the ID3 v1 tags, which are limited to 30 characters. Picard usually writes ID3 v2.3 or v2.4 tags, but can also write the v1 tags additionally for compatibility with older players. Unfortunately Windows Explorer still does not cope well with ID3 v2.4 and you should use v2.3 if you want Windows Explorer to display your tags. You can configure this in Picard Options > Tags > ID3v2 version
On a side note: It is really disappointing Windows Explorer in 2016 still does not deal with newer ID3 tags. But it is possible not surprising, given that this software does also not deal with long file names and is also part of the issue discussed in the "filename gets cut off" thread.
