Hi,
It looks something related to the CSS and the way than the button/link is handle.
If you take a look at the color text you will see that you can turn it "green" (instead of blue) and when you have that color, you can click on the real link.
I place a blank square in that screenshot to indicate you one spot.

Afterwards, I think it will require some tests and modifications in the CSS to fix that issue ; but like that I don't know what CSS rules can generate you that issue in your website (your template).
If required, you can perform a view override for the toolbar and change completely how the button are displayed.
