Default_tags and volume_tags

Hello,
for some reason the volume_tags do not “get” the values from default_tags. Is there something i’m missing?

e.g.:

locals {
  base_tags = {
    Client                = var.Client_abbr
  }
}


resource "aws_instance" "this" {
...
  tags = merge(
    {
      Name          =  "Blah"
      Team          =  " Blah" 
    },
    local.base_tags
  )

  volume_tags = merge(
    local.base_tags,
    {
    Name          = "Volume_Blah"
    Team          = "Volume_Blah"
    }
  )
}

and

provider "aws" {
....
 default_tags {
    tags = {
      Solution              = "comp"
    }
  }
}

Only VM has “Solution” tag.
“Name”, “Team” and “Client” are present on VM and volume.

Thank you,
