Catacombs bug? Dock town

Hi all. Really struggling and suspect a bug (which i dont know how to report) i cleared the catacombs previously and now re-entered through a portal. I figured out i need the crystal from the starting point bridge to use on the other slot where the focused beam is hitting... i brought the crystal over but i suspect theres a height/proximity issue preventing me from slotting it in. When you have one equipped you cant jump so Ive mo idea how to combat this. Has anhone else had the same issue and knows the fix ?
