Problem with the portfolio of GridStack theme


Hello, I have a problem with the portfolio of theme in question on the site The home page filters are displayed incorrectly: by selecting “ALL” is only displayed the “CLIENTS” filter contents while the other filters do not show anything. I confirm that each filter has more content.
In addition, if I click the “CARICA ALTRI PROGETTI” filter, in botton position, some content are duplicated.
How can I fix? Thank you.


Authors forum is here - he has a great support policy. Be aware he is US based and timezone but send them a message there and I am sure it can be sorted easily.


Thank you!
