Ошибка SE::Google - при использовании Slow Engine значения полей Location и Extra Query игнорируются

[Support Alex]

The "Location" and "Extra Query" values seem to be ignored when using the Slow Engine. Slow engine works with Mobile Google but I can't pass those two parameters to set location so results are not correct.

I also tried using the "x-geo" header for "Additional headers" setting but that doesn't seem to work either.
