My structure keeps on getting EXTREME SOFT STOREY even if i already reduced the storey heights and increased the beam and column sections. Please help me. Thank you.
To know how the story stiffness calculated please refer below wiki.

Also I would recommend using the latest version 22.08.00.175 to check the issue as suggested earlier.
