RODI not removing ammonia

[Hawaireefer]

For some reason our tap water has ammonia in it. However, my RODI system doesn't seem to be removing it, even after I've replaced and flushed out the filter. I know the test kit is working because I tested another water source, and there is no Ammonia. I've been using prime to detoxify it (btw can anyone confirm that prime actually detoxifies ammonia?), but I want to not have to worry about it anymore. Does anyone know why the RODI is not removing the ammonia, or what I can do to remove it?

Make only one post for questions. It will eliminate confusion for us trying to answer multi post.
When was the last time you changed carbon blocks or the di resin? Anything that got past ro membrane should be absorbed by the di.

@Randy Holmes-Farley does carbon block remove amonia. Does chloramine show up as amonia on test kit.
