my highlights messed up when I open the same website again

Hi there,

I have a problem for a long time, which is described in the title. The example is as below. 

The highlights should appear like what is stored in the "Liner" account, but when I open the same page again, the highlights show like this

So, the highlights are totally messed up, which makes me frustrated. I hope someone would fix this problem or I may consider canceling the premium.

Thanks
