Using delete key on Mac - Teamviewer 14


Hi all, 

I'm using a Macbook Pro to remotely connect to a PC. I'm using Teamviewer 14 on both the Mac and PC. However - the delete key doesn't seem to be working. I can use ctrl c and ctrl v just fine... and I can also backspace just fine (by pressing the "delete" button on mac). But when I press cmd+delete on my macbook to delete files, i'm unable to delete anything on the PC. I have to right click and then select delete. Super inefficient! How do I get this to work?

Please help!
