Name custom field changed automatic afte saving.

-- HikaShop version -- : 6.1.0
-- Joomla version -- : 5.3.3
-- PHP version -- : 8.3

Dear Support,

When we create a new custom field and select Table: item, then choose field type: customtext, and enter Column name: finishing_text, the column name is changed to a strange naming after saving. See screenshot.

There is a workaround to prevent this: first choose field type: text and later change it to customtext, but that doesn’t seem to be the intention.

Is this a bug?
