There are 5 items in this tab!
If you click on tab number 2, cat sits, then suddenly cat sits moves over to where tab item #1 was:
The tab just moves over to the left like 100 px, and dog sits replaces where cat sits was.
If you click on tab number 3, day sits, then suddenly cat sits and dog walking stack on top of each in a jumble of text.
I hope you can dive into the read only link, inspect the structuring of the tab, and help with a solution!
The tab is on the page titled 'Home'.
