Reactions on pin points on x and z axis during seismic and wind loads

Dear community good morning,

On the below steel structure where only vertical loads applied (self weight (DEAD) + piping elements (DEAD)), when i post processing the model , during the combinations where wind and seismic loads applied, i see that on the reactions field on the pin points supports (4 corners), i have very less reactions on x and z axis. See below the relevant screenshots.

Also below you can see how i have already set the parameters in wind and seismic responce menus.

Is there anything that i should change?

Thank you very much in advance for your valuaable support.

Kind Regards,
