Sorry to hear of the problem you are having.
I have tested it on my test site and it’s working fine for me using latest version 1.2.2 of Gillion theme.
Could you please share me your site URL where it’s happening so that i can troubleshoot it?
This can be due to plugin conflict on your site so please try temporary deactivating all plugins except Unyson plugin and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
It misses the font sometimes as well. Besides, could you guys consider adding options to enable/disable icon library because a lot of time people do not use them and the server still load all files, which causes even a few seconds slower.
