[Resolved] No products were found in SHOP of second language

MY site hidden link
show products correctly, but in second language, there is no product hidden link

and it is not work after change theme o 2017 and stop all the plugins. (My theme is Sober)

Moreover,
hidden link
it shows No products were found matching your selection. (没有符合你要求的产品)

it seems that URL with the end of /?lang=zh-hans has problem,
tc-designer-series-cn is the translation of tc-designer-series
and in category, the count of tc-designer-series-cn not zero, it show that tc-designer-series-cn has products.

for the page hidden link, shows 10 products.
