button shape and text alignment changed after updating

Question

I have recently deleted and re-installed python, kivy, kivymd. Then, my kivy button's shape changed. My MDRaisedButton used to have slightly rounded corners but now it is very sharp. Also, My MDRectangleFlatIconButton had icon and text aligned in the center but now it is located on the left side. I can't move icon and text in the center of the button.

Has there been any update among kivy or kivymd recently? I can't fix my problem now.

My python version has been 3.10.4 always. but i think Kivymd could have been updated.

Would you help me to put icon and text in the center of MDRectangleFlatIconButton? Is it possible to modify MDRaisedButton with rounded corners?

I appreciate your help.

Pip freeze:

My old looks: icon and text centered

New look: on left side. i can't locate them in the center
