My push date-automation doesn't calculate properly

Hello Everyone,
I am new in Monday.

I tried to create an push date-automation, but i experience a problem with the automation.
P.S This is multi level board.
The webinar is at 26 march and i want the automation to calculate the days i am writing in the table, for example when i write -25 days i expect that the automation calculates -25 days which would be 1st March, but the automation calculates at 1 February.
Also when i write 1 day, which is supposed 1 day plus to be added, it still calculates Minus instead increasing.

Here is image of the automation:
