Why won't my website switch to the Malaysia version on first click?

Hello,

My page has this issue whereby being in the Singapore network on the Singapore site (https://sg.heychips.com), clicking on the Malaysia button from the globe icon goes to https://sg.heychips.com/?shpxid=16110c95-b98f-42d2-b85c-1d883d2f93a2 rather than https://my.heychips.com even though the code specifies https://my.heychips.com in the href.

MALAYSIA

This issue is also better illustrated in this YouTube video.

Wondering if anyone has the same issue and has a solution to this. Any help will be appreciated, thank you!
