Hi Rivet!
Thanks for contacting us. I will gladly help you with this issue. First, I need a little more information to test this in the browser.
Can you try switching to the default theme of 2017 to see if the issue continues?
Also, can you provide us with your system information to better troubleshoot the issue?
Below is a help guide in case you need it.
