Invisible Buttom still shows text

I am working on my first captivate project, and I ran across this problem:

I have a multi-state Smarktshape-Button. It's a simple rectangle with a text on top. both change colors depending on the integrated state roll-over.

This button is then hidden / made visible with a different button in my navigation.

By default it is not visible and is both marked as invisible in the object's properties (eye icon next to its name) and in the timeline. It is however set to show for "rest of project" due to its link with the navigation.

So far everything works fine.

My problem is that this only hides the rectangular shape of the button but not the text in my project view. When publishing the project everything works as expected, but while working on the project I have the text of the button square in the middle of my project at all times which is rather annoying.

In this state it behaves as if it was invisible as it's not clickable, but it never disappears. A restart of the program and my computer did nothing to fix this.

Does anyone have an idea as to what might cause this?
