Double Layout Section on cell phone

Dear Community,

i see columns of the old theme layout on the iphone. It is not visible on the iMac. I have cleared the cache of the chrome browser and the mobile phone. I searched the columns in the Elementor. Nowhere is the layout hidden or duplicated. Why do I see it twice on various media? For example, the last column with the content button. And only when the cell phone is across. Thanks for every answer. Greetings

Its the Hello Theme and im working with the elementor pagebuilder.
