Translation stopped displaying Options

[SunitDattani]

Hello, the translations on my store had stopped displaying. 
I had hired a freelancer for some changes to help with pagespeed about a month ago. Translations were working fine after they finished their job and access was also removed, but suddenly translations stopped working about 1 day ago. 

Can anyone figure out why? 

I haven't made any new changes to apps / theme.

I see that if I try to change theme to another theme on preview - my translations still don't show.

link to website: www.regencyspices.hk there is a Translation Lab switcher on the top, but even though translations are there, and it goes to the translated URL, none of the translations load.
