Issue With Advanced Product Sorting

After we select a different sort option in the product list page, the loading mask keeps spinning when layered Navigation ajax option is set to yes.

Error in the console is: Cannot write a value to a ko.computed unless you specify a 'write' option. If you wish to read the current value, don't pass any parameters.

When Ajax is disabled from the layered Navigation option, everything works but we will like to use the ajax as it saves time on load.

Also, I don't see anywhere to submit a ticket on here.

Thanks in advance for your help
