Portfolio not behaving correctly

After setting up a test porfolio, I'm getting the following errors:
Notice: Undefined variable: module in /home/ra0002/public_html/site_joomla/modules/mod_jux_portfolio/helper.php on line 24
Notice: Trying to get property of non-object in /home/ra0002/public_html/site_joomla/modules/mod_jux_portfolio/helper.php on line 24

and in the console:
Uncaught TypeError: jQuery(...).tooltip is not a function

As a result, sorting is not working and thumbnails are displayed as such:


I'm using Joomla! 3.4.1 Stable.

Hi,
This problem caused by jquery,
I've edited a few lines in the file default.php
Currently the portfolio was operating normally!
