To edit a contribution in the team treasury, first go to the menu item "Treasury" and then to the tab "Contributions".
It is important to note that you can only edit contributions if there has been no action on them yet. An action is executed when you click on one of the gray circles. If you click once, a green tick appears, symbolizing payment. The second click changes the symbol to a gray "one-way sign" symbol, which stands for the liberation of the respective member. A third click makes the original gray circle reappear, signifying that the contribution has not yet been paid by the member.
If you scroll down in the tab "Contributions" you will find the button "Manage contributions". Click on it and you will see an overview with all created contributions. Now select the contribution you want to edit. A second pop-up will open, which is called "Details". In the lower part of the pop-up there is a button that says "Edit". If you click on it, you can edit the title or the amount.
Note: If you want to edit a contribution, although you have already performed an action here, you can use the archiving function. This will make the contribution disappear from the overview and you can create the contribution again and correctly. It is important here that all circles are first brought to the original form (gray circle). Otherwise, the amount will remain in the team treasury. How to archive a contribution, you can read here.
