product title with taxonomy autocomplete(labeling) doesnt work

If i use taxonomy with autocomplete labeling and i create a new label for taxonomy using labeling in inline entity form the prodcut title wont be good.

For example:

There is a taxonomy called "color". The taxonomy contains 3 colors, red, blue and green. If i add a new one for instance the yellow then my product title wont be generated properly. There wont be the "yellow" in the the title like: "my product title (yellow)" but "my product title" so the "(yellow)" is lacking.
