After creating a new project based on this template, I founf that there're a lot of tasks didn't have the correct dates, they didn't correspond to the initial date of the project + start after days.

Here I have a example:

I have these two tasks set in the template:

When I created a new project, the second task just had a date that has nothing to do with the setting in the template:

Here is the dependency relation of these two tasks. I know you guys have already explained me that your dependency setting only supports end-begin and when it's not like this things may be weird, but in this case, since I have a task's "start after" days set in the template and this task does not depend on another task which has a later start date. I just don't understand how it happens?
