android - Constraintlayout always uses left/right instead of start/end and then instantly shows me a warning -

when use constraintlayout , set margins drag&drop toolkit, automatically uses marginleft , marginright , instantly shows me warning, should consider marginstart , marginend instead.

can somehow set automatically using start , end?

i noticed, uses app:layout_constraintleft_toleftof="parent" instead of constraintstart_tostartof

but 1 doesn't show me warning. however, tag not working on rtl layouts.
