I can confirm this situation too. When I choose Features/Logo type: Image => I get a duplicate logo on homepage and this is loosing the centered position and is displayed on the left. This is happening even with the native Events logo (.png). so I'm sure that we are playing with a bug or something.
Going further, I tried one of the advices from the developers and I modified the CSS file by changing .svg with .png. In this case, the Home page looks great, no problem at all, but when the top menu is displayed and the logo goes to the left side, then something strange is happened: the logo become stretched somehow and it's loosing the correct appearance.
I'm kindly ask anybody who can investigate this to come back with a solution.
Thank you in advance.
