What does that have to do with anything? Is this some kind of purity test for you? During their 30 years of independence, Ukraine has struggled with corruption, authoritarianism, two revolutions against authoritarianism, and a Russian invasion. They've had bigger fish to fry at home than to cast judgement on neighbouring countries.
According to https://en.wikipedia.org/wiki/Armenian_genocide_recognition a total of 34 countries have recognised the Armenian genocide as genocide. That's not a lot. Even the UK and half of Scandinavia haven't. That Ukraine hasn't means nothing, it doesn't mean they don't consider it genocide, and it certainly doesn't mean they're okay with genocide. You're being overly anal about this issue.
