More than one mask doesn't work

 Hi

I'm using an M1 Mac with Pr 2023.
I'm trying to use two masks to hide the two black rectangles above and below the text. 
I used the pen tool to create a mask path(Mask1) and it did its job. But when, on the same clip, I use the pen tool to create another mask(Mask 2) for the black rectangle below then instead of masking the area, Mask 1 comes undone and selecting and deselecting the invert mask option either makes the other masked area visible or hides the text.

Can't one layer have more than one mask? And what is the correct way to use them to have the desired effect?
Thanks

That is correct, you cannot use more than one inverted mask.

Mask on the Alpha Adjust effect.

Hello

Thank you for replying. I wanted to know further. Why can't we use two masks on one clip? And what is the alpha adjust effect that you mentioned?

Thanks!

Why? You need to ask Adobe.

Alpha Adjust is found in the effect panel: all is explained in the screenshot.
