Welcome to the community, @tuhifi!
Maybe you will need to clear the cache of your browser. This should solve your issue.
I tried another browser but same same issue. I removed Google Chrome and reinstalled it. Still same issue. So i think clearing the cache noe a solution for this.
@tuhifi, maybe try it on a different PC to see how it behaves?
