Cannot seem to export or save as to SVG with objects inside the artboard (for repeatable patterns)

Hello,

I have been trying relentlessly to save as or export my artboard to be used as a repeatable pattern.

I have objects that move over the artboard line and therefore need to only save what is within the artboard.

I have tried export and save as, for SVG, ticking the checkbox each time for "use artboard" but it saves all of the objects outside the artboard.

what could possibly being going wrong here? thanks
