Bundles cost 0rp Bug (I sent support a ticket and they said come here)

Last night I was playing league of legends and after making a purchase of the Digital Collectors bundle my shop looked like the attached picture. I made sure not to actually use it for anything but I did feel concerned so I wrote a ticket to support and they said to make a thread here. I have the items that were left in it when purchased written down and can post the exact process if asked to by a Rioter but I would like to avoid giving an exploit out to the public so if there's a better way please let me know!
