how to make changes in one board only in a project?

[Hiba Abdin]

created a new board in an existing project and it seems like a copy from the old board.
the problem is when i make changes to board two they happen to board one, and it's something i need to stop

Boards are not containers for issues, nor are issues part of boards.  A board selects an issue and displays it.

When you change issues that appear on a board, you are editing the underlying issue.  Not the view of it.  Because you are altering the issue, anything else that shows the issue is going to show your change, because you've changed the issue.

What you're asking for is self-contradicting (and would render it utterly pointless using an issue tracker) - you are asking to change an issue and not change it at the same time.

Hi @Hiba Abdin ,

Boards are basically a visual way how issues move through its lifecycle. Therefore if you have a issue that shows up two different boards, then if you make changes to one board, then it is expected that the changes reflect to the other board. 

For example, if you have a board that pulls all issues from "IT Project" and another board that pulls all issues from "IT Project" with Issue Type "Security Access", and you have an issue called IT-124 which is "IT Project" with Issue Type "Security Access", then it is expected that it shows up on both boards. So if you change the status from "To Do" to "In Progress" from one board, then changes will reflect on the other board for the issue IT-124.

Boards don't store separate data of issues, they simply pull the data from the issue itself.
