[SOLVED]Connection Issues

[Victor15]

Hello there!
I'm new in Altium, I'm using the 19.0.15 versions, only in this project it's happened, not in the others.
I've placed some components in the PCB, but need to change their position, it's ok, but the old connections lines still there, like the image:

Someone can help me with this? how to delete these lines?

Did you already try 'Clear error markers'
Maybe Hide all nets then Show all nets, under view menu.

If it still persists may be necessary to copy the information to a new PCB file or similar.

Do you have any components on the bottom layer and the bottom layer is turned off? Try turning on the bottom layer.

No, all the components are in the top layer, these markers whore about the last positions off then.

Thanks, Bro I really don't know the function "Clear error markers", thank you a lot!! it's worked perfectly.
About the Hide all, I tried this, but without success
