TYPO3 - Contents are displayed twice on translate - typo3

Question

I'm using TYPO3 9.5 and I'm trying to translate page using the Copy process from TYPO3,
The Problem that the content are displayed twice when I change to other language beside the default language (EN).
languages:
-
title: English
enabled: true
languageId: '0'
base: /
typo3Language: default
locale: en_US.UTF-8
iso-639-1: en
navigationTitle: EN
hreflang: en-US
direction: ''
flag: en-us-gb
-
title: Deutsch
enabled: true
languageId: '1'
base: /de/
typo3Language: de
locale: de_DE.UTF-8
iso-639-1: de
navigationTitle: de
hreflang: de-DE
direction: ''
fallbackType: fallback
fallbacks: '0'
flag: de
In my config I have tried to use: languageField = sys_language_uid
select {
orderBy = sorting
languageField = sys_language_uid###
where = {#colPos}={register:colPos}
where.insertData = 1
pidInList.data = register:pageUid
pidInList.override.data = register:contentFromPid
}
But will always display the default language(EN) but if use :
includeRecordsWithoutDefaultTranslation = 1
The content will displayed twice in the Default language and the selected language .
Edit :
config {
absRefPrefix = auto
no_cache = {$config.no_cache}
uniqueLinkVars = 1
noPageTitle = 2
linkVars = L
prefixLocalAnchors = {$config.prefixLocalAnchors}
renderCharset = utf-8
metaCharset = utf-8
doctype = html5
removeDefaultJS = {$config.removeDefaultJS}
inlineStyle2TempFile = 0
admPanel = {$config.admPanel}
debug = 0
cache_period = 86400
sendCacheHeaders = {$config.sendCacheHeaders}
enableContentLengthHeader = 1
intTarget = 0
disablePrefixComment = 1
index_enable = 1
index_externals = 1
index_metatags = 1
headerComment = 0
contentObjectExceptionHandler = 0
compressJs = 0
compressCss = 0
concatenateJs = 0
concatenateCss = 0
}
The Problem was solved for the double content in the config yml :
fallbackType: strict

Answer 1

The options languageField and pidInList will be detected automatically to match the current page and language while respecting the table you are trieng to fetch. For testing purposes you may only use "< styles.content.get" to fetch the content of colPos=0 of the current page.
However I think your problem is located somewhere else in your configuration. Do you also setup some language settings of the config.-Typoscript-Section like sys_language_uid depending on the "L"-GET-Var?
