TYPO3 Core

The TCEMAIN configuration to disable the "[Translate to %s]" prefix for pages or tt_content data is not respected anymore.
Each translation has the configured translation prefix. It does not matter if the configuration exists or not.

Affected T3 versions: 8.7 LTS, 9.4

TCEMAIN {
  table {
    pages {
      disablePrependAtCopy = 1
    }
    tt_content {
      disablePrependAtCopy = 1
    }
  }
}

• Create an alternative page language
• Translate the default page in the page module in the "language mode" and the dropdown (available languages)
• The tca form for the new page language is beeing loaded and the "title" field has a prefixed value

• Edit a tt_content element
• Click the dropdown for a new translation of the current content element
• The tca form for the new content element is beeing loaded and the "header" field has a prefixed value

This issue may also be related when using TCA columnsOverrides.
