Resolve some issues in Joomla website with sp-builder module

I have a project with some issues: 1) logo with wrong url in english version 2) Menu in english version is not visible in iphones 3) Select combo to change the language is not visible in iphones 4) In a submenu option in header the default selected language combo is changed the name of language, instead of English said Spanish and viceversa. Only in home is working good the name options, In internal versions the selected combo to spanish is not working. When I am in internal section and i change to another language it is redirect to home instead of the last section I was. 5) In mobile version the logo is very small
