How to use the portfolio widget in two tabs of the Tab Widget

Hi, I’m using Phlox Pro theme and with it I receive Element Pack. The situation is the following. I used a tab widget from Element Pack. I created two tabs. In those tabs, I used the portfolio widget from the Phlox Pro theme. So each tab contain per one portfolio widget (they are loaded as template sections, I even try with AE Templates). Both portfolio widgets are supposed to show different projects, but the problem is that one of the portfolio is not visible. What is the problem?
