Does not delete record in Base table

Hello
I use LibreOffice Base Firebird, with .fdb file.
In a table I have changed the type of a column from INTEGER to VARCHAR and the size from 10 to 20.
The field stored correlative numbers. Now the format is 2026-N-OOO1.
I have managed to import the data. The queries, forms and reports work without problem.
The problem now is that I cannot delete records, neither individually nor by selecting several.
The delete record menu does not appear, they are only displayed:
Table format
Row height
Copy

Thank you and best regards.

You could update records, add new ones and are missing the function for deleting records?
Please add a screenshot - don’t know if you are trying this in a form, a table, a query…
Also: You are using a Beta version of LibreOffice. I would do this only for testing, not for reals work.

Does your table has an id-column?
.
I can read imported tables without id, but I can NOT change/delete any individual records (except for dBase).
