Accordion Blocks not closing

Hello!
Working in 7.1, I am using accordion blocks to reveal bios beneath photos. When viewing the page, I can open any one of the accordion blocks, but it won't close and once it is open, it is not possible to open any of the others.

Can someone help please? Thanks!

For the accordion block descriptions, you can select "Allow multiple open items" by clicking into edit mode on the block, selecting the "Design" tab, then toggle ON the selection. 

Accordion blocks can be a bit finicky, sometimes you have to click directly on the Plus Icon in order to open or close. Try this out and let me know if that helps!

Lastly, a good old rebuild sometimes does the fix if it still is giving you trouble. Meaning, delete the original and rebuild using a new accordion block.
