How to turn off filter before saving?

[KT]

Hi all,

I am working on a project which uses several filters. Before saving and
closing out the project, I change the filter back to "Filter for: All tasks".
But when I open up the project the next time, it directly starts with the
filter constraints instead of opening up the project in the default Gantt
chart view. I am not sure what I am doing wrong. Please suggest me to get rid
of the filter and open the project clean in the default mode.

Any suggestion is highly appreciated. Thanks in advance.
