annoying undo problem

Hello everyone.

I have found that when I was sculpting with a texture and I've changed the setup for one that I needed ( for example from stroke - space to anchored, and others, strength from x.xxx to y.yyy I change Falloff option for different) and when I have done my first sculpt move and after that I used ctrl+z my last sculpt is removed but also all the options are reset to the previous ones. It happens all the time with my first sculpt move in this situation.

I've recorded a screen share video to show this glitch. I've presented it few times with different option setups.

If anyone could check it, it would be nice and helpful.

My Hardware: Win7 64bit, Nvidia GeForce GT 730 2GB, AMD 6300 SixCore 3.5GHz, 8GB Ram.

Thanks
