Some display and CSS issues

Hello,

I am news on Enfold but I have some css & display issues on your theme.

1. The logo is pixeled even I uploaded it in a high resolution format
2. The image gallery is not displayed properly as you can see here: https://corporate.tutuionatan.ro/portfolio-item/zeed-dent-clinic/
3. On mobile, on team section, the images of the team members are not dispayed
4. The logo is not aligned with the menu and social icons

Extra question:

Can I change the slug of the image gallery items? I want to translate it from portfolio-item to proiect.

Thanks
