Filter icon/button not visible if folder name is too long

Hi.  
If a folder name is too long, I can't edit the "filter" because the filter icon is hidden.   Is there a way to get around this?  
No matter how high I set my resolution, I do not see the filter icon/button, only the "favorite" button.

Here, with a short folder name, I can see the filter button:
 

Thanks
Rob
