in the AGO option tab Tools, subsection Tools:
there are several presetted links. If you delete an entry in between and look at the result, then you can see
- Infopanel shows all links except the deletet one
- Ago menu just shows the first few entries and hides the entries after the deleted one

so if you create a new entry (fill the emty slot from the former deleted one) then it is displayed normal again.

you could solve this issue by making checkboxes for the presetted links (like in every other subsection in Tools)

p.s.
there is still a broken/undefined subsection headline "T60" between the subsections "Simulators" and "Combat reports"
p.p.s
the link for "sharing of gain" is broken
