ControlNet inpainting problem, don`t work.

Hey guys!
thanks for this great work and update!
I successfully used most of the Controlnet models on photoshop, like canny, depth...even the newest tile model. but when i try the last and most important option: inpaint, it don`t work.
The steps and images are as follows:
1. generate 1 cat ( 512 x 512)
2. enable controlnet, choose inpaint and inpaint model. then click "set CtrlNet"(plz Ignore openpose on the image)
3. give a new prompt on T2I, then click generate

4. that`s the problem, it only can generate the some image i give to "set CtrNet". it`s looks like no mask on inpaint model, but i don`t find where can i draw a mask?

5. even i screenshot form another image on "set CtrNet", it only "copy" the image. not "inpaint".
Any idea what I'm doing wrong or how to fix it?

BTW, then I choose "reference", I still can choose other models on the right. you know the reference no need model, if choose it, it`s can`t work. maybe the model options can add a "none" option?

Best
