@echo off

echo Select a language. (de/en)
set /p language=
IF /i "%language%"=="de" goto languageDE
IF /i "%language%"=="en" goto languageEN
echo Not found.
goto commonexit
:languageDE
echo German
goto commonexit
:languageEN
echo English
goto commonexit
:commonexit

The point is that batch simply continues through instructions, line by line until it reaches a goto, exit or end-of-file. It has no concept of sections to control flow.
Hence, entering de would jump to :languagede then simply continue executing instructions until the file ends, showing de then en then not found.
@echo off
set "language=de"
IF "%language%" == "de" (
goto languageDE
) ELSE (
IF "%language%" == "en" (
goto languageEN
) ELSE (
echo Not found.
)
)
:languageEN
:languageDE
echo %language%
This works , but not sure how your language variable is defined.Does it have spaces in its definition.
batchfiles perform simple string substitution with variables. so, a simple
goto :language%language%
echo notfound
...
does this without any need for if.
Recommendation. Do not use user-added REM statements to block batch steps. Use conditional GOTO instead. That way you can predefine and test the steps and options. The users also get much simpler changes and better confidence.

IF %ExecuteSection1%==0 GOTO EndSection1
ECHO Section 1 Here
:EndSection1
IF %ExecuteSection2%==0 GOTO EndSection2
ECHO Section 2 Here
:EndSection2
