Problem footer layout after installing update

Hello,

After installing the update (version 2.2.0.1) I have noticed that the layout of my footer widget area has been changed. The footer area had become too big, the space between the different text items has become too wide, the separator lines between the footer columns (white line) has disappeared and the separator lines between the several links has disappeared, the font of the widget titles (CONTACTEER ONS, NIEUWS, BEL MIJ and SNELLE NAVIGATIE) has become too big.
Would it be possible to advise me on how to correct the footer area? In short I want to make it smaller, restore all the separator lines and have a smaller font for the widget titles.
I’m working with a child theme. Link to my website: http://www.elitor.be
PS. Maybe good to know: I have already had some issues with the footer area (colour, height, …) and after contacting your support forum I was advised to insert the following css:
#footer.dark-style .widget-item h4 {color: #383838 !important;}
#footer .widget-colum { border-color: #FFFFFF;}
#footer .widget-column { max-height:300px !important; }
#footer { padding-top: 30px; }
#footer { padding-bottom: 60px; }
#copyright-wrapper a { color: #000; }

Best regards,
Sophie
