Small logo in Header

Hi,

Im having a problem in my website with the logo in tablet and mobile, the logo is too small and i can´t change it.

I tried increasing the logo size from the identity section but nothing happens.
I tried diferent images for the logo and stays the same.
Finally, if i choose use navigation as header i get a small logo in desktop too.

I don´t know what else to do, if i decide to not using the mobile header, i get logo above menu, but i cant put them in the semane line.

I hope you can help me,

Thanks in advance.
