About us moves logo and navigation

Hi everybody out there in Shufflehound-universe,

first of all: Wow! Great work! Thank u so much!

I installed maskitto-light and since i am trying around i noticed some issues and wanted to ask, if you can lend a helping hand:

I used the pregiven “About us” page and adjusted text. Since then the template is “hopping” when you klick on the link. What did i do wrong? (All other links work well)

Thank you so much in advance!
