What steps will reproduce the problem?

1. Change any options with regard to displaying Tanks, Targets, and Targets-of-Target; all three are always shown regardless of settings.
2. Change the "number of tanks to display" option; all tanks are always shown regardless of settings.

What is the expected output? What do you see instead?

I would expect that if the number of tanks option is set to zero, that no tanks are shown. I would also expect that if I uncheck the options to display tanks' targets and tanks' targets' targets, those are not shown. However, everything is always shown regardless of settings.

When the number of tanks is set to zero, the frames do disappear briefly, but then reappear a second later, and then repeatedly flicker in or out every few seconds or less.

What version of the product are you using?

r30, downloaded from WoWAce project page.

Do you have an error log of what happened?

No, as no Lua errors were generated.
