Accordion header issues with Enfold 6.01 (constant value refresh)

Hello,
I use Enfold for a while and encountered some strange issue with accordions when updating to the last 6.x versions.
The header text value is being continuously set for every single unopened accordion element. Looking at it in the browser inspector, I can see my elements’ HTML representation flickering as the header is repeatedly being changed to the exact same value. Is there some sort of callback or update function that shouldn’t have been called? I can imagine this being a symptom of deeper performance issues too.
Thanks in advance.
