Version mishmash?

Hi,
short remark of two different official versions: Last version of Hueman theme to download from:
– ww.wp.xz.cn is 1.5.4 (https://ww.wp.xz.cn/themes/hueman/)
– Theme homepage is 2.2.3 (http://alxmedia.se/themes/hueman/

My WP does not offer an update of theme (my is 1.5.4).
What is the right/last one and is this issue right?

PS: Really thank you for giving an opportunity to being a Hueman.

Regards
