There are errors in the basic data entry of the project you added: Unnecessary slab edges were entered, slab edges constantly divided the foundation, and small foundation pieces were formed under the columns. However, the corrections you will make will not correct the insufficiency of the section, because the raft foundation system will not be economical in this structure with a single span of 24*11 meters. Due to the size of the raft foundation, even the system's own self-weights cause a cross-sectional deficiency for the front dimensions you choose. I don't know how many floors there are on the top floor, how much load will be on the foundation, but it seems more logical to apply a single foundation.
