That line looks correct, so most probably the errorList still contains
1, that's why it remains red. Note that if you change something in the
data-model, you are expected to re-wrap it, i.e., in practice, call
Template.process(...) again, or else the internal (wrapped)
representation of the data-model may reflex the old state of the
data-model.

Another possibility is that the template output (the whole page most
probably) is cached somewhere outside FreeMarker. FreeMarker itself
doesn't cache output.
