Screenshots not uploading with SVN commit

I just published an update to my plugin ‘Tyme Social Count’ (https://wordpress.org/plugins/tyme-social-count/) which included screenshots in the ‘/assets’ directory. The screenshots show a ‘?’ when I type svn stat and when I commit the screenshots aren’t uploaded. I then tried to move the screenshots to the ‘/trunk’ directory, which is what my ‘Stable Tag’ points to and they still don’t get uploaded.

Any idea why the screenshots are not being pushed with the commit? How can I get them uploaded to the plugin repository with my plugin? The README file has the correct directives for the screenshots and everything.
