It appears that the carousel arrows used to navigate are missing on the homepage.
Firefox 68.7.0esr (64-bit)
MacOS version 10.15.4 (19E287)
uBlock Origins (1.26.2) is installed (but disabled for this site) it is also installed on my Windows machine and I have the nav arrows present there. (Also running Firefox)
I've noticed it appears that the cursor knows an element should be there, as when I hover over the spot where the arrows should be the cursor changes (screenshot included as well)
I've checked for Firefox updated and it states I'm up to date. This computer has also been restarted recently and it still persists.
Included below is a screenshot of my homepage
