Text association creating new column

[rkenjiibmsuser]

I create a new CDS view to field as semantic text:

define view entity zt001 as select from t001
{
  key bukrs,
      @Semantics.text: true
      butxt
}

After that, i created a CDS view to expose data with text association:

define view entity ztest as select from t001
  association [0..1] to zt001 as _zt001 on $projection.bukrs = _zt001.bukrs
{
    @ui.lineItem: [{ position: 10 }]
    @ObjectModel.text.association: '_zt001'
    key bukrs,
    _zt001
}

When i execute it, the extra column with description of company code is generated:

I try to remove association at end of CDS ztest, but the text association doesn't work in this case.

How can i remove this column "Company name"?
