Hi, I’m using the Nominee theme. The site is https://alison4dro.com. I have my themeforest code if you need proof of purchase.
The sticky menu is not working well – it is jumping when you scroll back close to the top. 
I feel this may be happening because I added a larger logo that what is supposed to go in the header, but I do need the logo to be this size.
Help please? Do you have some CSS code I can add?
