X Theme, revolution slider, enviro gallery are all updated to the most recent versions. However, when I edit the page in cornerstone and attempt to add the elements for either revolution slider or envira gallery, these only appear as "Classic Revolution Slider" and "Classic Envira Gallery" elements, no regular new elements appear for these. This Wordpress site if relatively new and I have not seem the new elements ever (so they did not disappear with an update or something).
I noticed an earlier topic discussing new elements not appearing as glitch, but then it said it was resolved with an update to X Theme. This topic was posted and seemingly resolved back in Nov. 2017.
The site is a GoDaddy "Managed WordPress Site".
