In the passage guide under Parallel passages, the passage references listed are not matching with what pops up when you click on them. They go entirely different verses.
Please post a screenshot (use the paperclip icon) showing a specific example.
I've just tried this on a verse at random and it worked fine.
Can you provide examples? This usually happens where Bible have different verse mappings. For example, in Jeremiah, there are different ordering of the passages depending upon the translation.
