Broken links in the user guide

Today I came across two broken links in the user guide (https://lynx.invisible-island.net/lynx_help/Lynx_users_guide.html):

https://lynx.invisible-island.net/release/lynx_help/cattoc.html

and

https://lynx.invisible-island.net/release/lynx_help/alphatoc.html

They both return 404. They are in the section "Main configuration file lynx.cfg" (https://lynx.invisible-island.net/lynx_help/Lynx_users_guide.html#lynx.cfg), and have the labels "by category" and "by alphabet", respectively. It turns out that they work when there is removed the part "/release" from their URLs. Also, I noticed that their working versions are also on the page, in the menu on the left. They have the labels "by Category" and "by Names", respectively.

I checked all other links on that page with wget, and only these two are broken.
