WP 34S binomial bug?

[lrdheat]

When entering binomial upper tail calculations, I get 1.0 for success=0 which is expected, but also 1.0 for successes=1 for k trials where k>2+. For example, rolling a 6 sided die 6 times, I correctly get binomial upper for 2 or more success as ~.26, but for 1 or more success, it comes up with 1 instead of ~.6 This is on version 3.3.3774, same on iPad 3.3T.3775
