KORIchiwa

Correct translations would be :

Packed mud - Спресований бруд
Wind charge - Вітряний заряд
Bundle - Мішок (And color variants are “<color> мішок”)
Trial key - Ключ вибробувань (In the current translation`s context is that the key is trial, like trial version)

Frogspawn - Жаб'яча ікра
Bogged spawn egg - Яйце призову загрузлого (Current translation means, that the spawn egg is bogged)
Warden and guardians are both called “страж”. Warden must be changed to “Боронитель” and guardians (Including elders) should remain the same.
Sculk sensor - Скалковий сенсор (In the actual translation it’s called acoustic sensor)
Calibrated sculk sensor - Калібрований скалковий сенсор (Actual translation is calibrated sculk sensor of vibrations).

I have a feeling, that they were using machine translation, as it's a typical error for machines not understanding the context of the original name.

Yes, this is still in the latest release and preview versions
