Sticky Menu drops to 2nd line

Hello,

Thank you for the plug-in, I’ve used it with other websites but for some reason I’m having issues with this one. When I scroll down the page the last nav bar category drops to another line. I tried to fix it but have not been able to and was hoping that you could help.

Here is the webpage: https://castlepineschamber.com/cpc/.

If you could assist with this I would really appreciate it.

Thank you in advance for your assistance.

Victor
