If someone interested after researching on the subject I found this on the link about saved views
learn.microsoft.com/.../saved-views
There are two size variations to the view selector:
Large view selectors – Pages that prominently feature a list will have a larger view selector for a few reasons. Most importantly, the larger view selector indicates the pages where the view can include user-defined filters and sorts. Because filters and sorts are included in the views, the larger selector size is also warranted as the view names will often be the best description of the data shown on the screen and the expectation is that users will switch between views more often on these page types. Grouping in a grid can also be saved to views on a page with large view selectors.
Large view selector that supports query modifications on the view.

Small view selectors – All other full-screen pages (except workspaces and the dashboard) have a smaller view selector that appears next to the page caption. Views on these pages include only personalizations, not user-defined filters. On these pages, the caption or record title is often the most important information at the top of the page. The smaller size of the view selector also reflects the lower frequency of view switching that is expected on these pages.
Small view selector that does not support query modifications on the view.

My case is small view selector. I guess, therefore, I can't save my custom groupings and totals calculations.
