shortFormVideos JSON has 2 videos but only displays 1 on ROKU channel

Your code is really bad. Please ensure it passes https://jsonlint.com prior to asking others for assistance. You closed out Short Form Videos with the ending bracket ] after bitrate of video 1 which is why only 1 video likely showed. It also didn't have an opening bracket for ID; 0002, also likely had too many closing brackets at the end too but the thing was a mess. I fixed it below.
