Premium stash tab upgrade not working

I bought four of these upgrades and not sure if they are working correctly. I have to right click the tab to get a tab number below the upgraded tab in order to change its color but the only thing that gets a color change is the border on the stash tab. The color of the tab where I can change its name DOES Not change color. What do I need to do to get the tab name to change color?

See this in the image here.

The tab is the jewelry tab which is the #4 tab.

I think you might be talking about folders most of the time you say "tab."

If you can't change 4's name or colour, that particular tab has not been upgraded.

Then how do you upgrade a Tab (those above where you place your items) after you purchase the Premium Stash Tab Upgrade?

As seen in this video https://youtu.be/NQT74Z5kMms

When you buy an upgrade the game will select a tab at random to apply it to.

4, 7, 8, 9, 10, and any other tabs not shown in your screenshot were eligible for upgrade.

Edit: I restarted the game and it resolved
