Answer:
In the second tab of the panel, increase the display factor of the "reaction forces". This should improve the display (see Image 01).
As an alternative, you can adjust the display properties using the menu "Options → Display Properties → Edit": change the size of the display in the "Results → Support Reactions → Nodal Forces" category. If necessary, you can also adjust the "relative limit settings" in the detail settings (see Image 02).
If you only want to display "Max" or "Min value" for the RC results, you can perform the corresponding setting in the Results navigator (see Image 03).
