Wrong Release Years

I noticed recently that the titles for many movies have been changed to include the release year and then the year for the film on its Listal page is changed to the following year. Here is an example: www.listal.com/movie/the-color-purple-1985. I have fixed a lot of them but they are still showing the incorrect year of release: www.listal.com/movie/bullets-over-broadway-1994

Here is another example: www.listal.com/movie/hi-mom-1970. And there are many that have the same year listed in the title and its Listal page: www.listal.com/movie/the-score-2001.

This is still an issue. Here is another one: www.listal.com/movie/cockfighter. Cockfighter (1974) came out in 1974 but on this site it is listed as a 2013 release, even the release date is - 19 January 2013. I checked IMDb and this is actually the release date for Japan. Hi, Mom! (1970) is another one I listed above, with its release date listed for Sweden (1 April 1980). I'm sure there are many more. Is there any way to change release dates?

pink flamingos page says it was released in 1986.
