Strange behavior of Feature Post Slider

Hi, I've only started to learn about wordpress and themes a few days ago so my apologies in advance if this is a user error. Using Catch Everest Free theme with WPGlobus translator plug-in. Everything translates perfectly between English and French, except for the Slider Title and Text. The Posts have both languages defined and when I go to Appearance..Customize, even the slider translation works just fine. However, when I exit (even without Saving), the slider on the published site is stuck on whatever language was showing in the preview. I can reproduce the error anytime. Thanks in advance for your help.
