I did some research on your page, and it seems you have overlooked one important step to get your custom texts to appear.
"Custom" is a text item that has to be enabled to display with one of the TEXT items. Just for testing purposes, I added it to the text1 module alongside TITLE+DESCRIPTION so you can now see at the top.
If you want it to display in a separate location, you will need to enable it in the TEXT2 module.
