TimeZone bug and many others, I need your Support

Hi there,
i’m new here, i bought your theme and i’m trying to setup everything fast because i have to open it to my community. So i will share with you all my problems and i hope you will help me.
1. Timezone Bug: When i set the time for Team Wars, it appearing UTC so if i put 15:00 the team wars will be at 17:00. My website clock it’s correct so what can I do?
2. When i’m navigating from mobile, i can see that image/text are disappearing, for example if you check the homepage from mobile, you can see that the part that show the video with the download button will disappear, strange right? Just from mobile, it works perfect from Desktop;
3. The Tournament widget is showing me the wrong date: “Tournament Begins: 17 Settembre 2019, 15:35” it just show the current time. How can i fix it?
4. If i change the Team Page template with a new one is not working, still giving me the old one. I changed it from wpbakery settings -> general settings -> teams -> my newteam template;
for now it’s all, i will add something else if i will find more bugs. Please help me, i need to open the website in 24hours
