Bugs/Glitches found when making diagrams

I want to know, why, when I’m using Visual Paradigm, some lines to connect “items” in diagram crosses and makes a horrible diagram. How to solve it if it is possible?

Dear 070221090,

Thanks for the post. We would like to see how is your diagram looks like to provide a helpful solution. Could you attach a screenshot to illustrate the problem? If you can’t post the file here, you can try contacting me via private message.

Best regards,
