Mixing Static Values Form_Cookies.Data

I tried to use static value=“Foreign” and dmx-bind:value=“form_cookies.data…” in the same input type=“radio”; after submitting the form, the value for that field was blank in the database.

Afterward I removed the cookies value from the input, and the static value was inserted into the database as it should.

What am I doing wrong? Can these two binding types be use together?
