There are a few issues with your post. You have not uploaded or linked to the pdf that you refer to. Your project is private so only you can see it. You have not provided the email address that you refer to. Publishing your email address is not encouraged on a public forum. The whole purpose of the forum is to help you with any questions that you may have. Direct contact is entirely down to the discretion of people who may respond to you. Direct Messaging people without having first obtained their consent is also strongly discouraged. You need to provide more information about what you mean by "separating a track". In EasyEDA Std, tracks are defined by net names. Any track with the same net name is the same physical track and cannot be separated. To split a track into two then each track has to have a different net name and this should be done in the schematic and then the PCB updated. Those two tracks are physically separate and cannot be joined.
