Trouble with Customizer Version 3.0.14 changing border color on tinyMCE table

I just recently upgraded my Cusomizer theme version to 3.0.14 for some reason it is changing to border color of my table to blue. I am using the TinyMCE plug-in toll to create my table. I have already tried to manually revert the border color inside of the TinyMCE table cell editor but cant seem to fix it. Please help…my site is wp.gentrifi.com the pages with tables inserted into them have a blue border color across the bottom?
