I suppose that you didn’t made update properly 
Edit:
As mentioned in another thread:
“Search the forum, probably you have to do fresh (clean) installation of last version. Suggest to follow documentation”
Another mention regarding manual update using SSH was to issue command opkg update first, only than opkg install *module-name* .
