Select with relationship and default value

Been stuck on this shit for hours. Ive got a select for 2 relationships on my Profile. I wanna have default values and using a custom setter. First off, no default value is displayed without '->selectablePlaceholder(false)', 2nd when i turn this off, the setter state is null. Any toughts? I would also like to have the fields searchable but I gave up on that long time ago. Having searchable fields removed my default values.
