Guys you need to improve documentation for your theme. You need to improve your support.
I have wasted so many manhours and money for internet subscription watching that no audio and no transcript video of yours trying to get this fixed.
Whereas a single sentence (that the Feature Element Tab title and Feature Content Element title must be same) somewhere in documentation or video would have saved me all the troubles I have gone through trying to fix this.
And, again when I asked for the support you were directing me to go watch a video with no audio and transcript instead of pointing out the fact that that the Feature Element Tab title and Feature Content Element title must be same.
