illegal command when files are present

I'm using the .conf next to the .zip of the same name setting

Game: Leisure Suit Larry 7 - Love for Sail

my .conf that calls LSL7DOS.bat in c:\LSL7DOS Relevant files and folder structure c:\ c:\LSL7DOS c:\LSL7DOS\LSL7DOS.BAT c:\LSL7DOS\LSL7DOS\SIER.EXE c:\LSL7DOS\LSL7DOS\CHECKCD.BAT c:\LSL7DOS\LSL7DOS\VESATEST.EXE

CHECKCD.BAT

@echo off
if not "%0"=="CheckCD" goto Abort
if "%1"=="" goto Abort

echo Checking for Larry 7 CD in drive %1:
if exist %1:\install\l7check.bat goto Exit
cls
echo Please put the Larry 7 CD into your CD-ROM and then
pause

:LoopCheck

echo.
echo Unable to detect the Larry 7 CD in drive %1:.
echo You may abort this looping test by pressing Ctrl-C or
echo insert the CD into your CD-ROM and then
pause
goto LoopCheck

:Abort
echo.
echo This batch file is used automatically by the Larry
echo 7 program. Please do not run it from the DOS
echo command line.
echo.

:Exit

My result:

Checking for Larry 7 CD in drive D:
Vesa found
illegal command found: sier

But SIER.EXE does exist, and it could find the CHECKCD.BAT and VESATEST.EXE

I tried to change the LS7DOS.bat but DOSBox Pure seems to persist with the above command Making changes to LS7DOS.bat will give the same issue. Since LS7DOS.bat is inside the zip, did Pure cache and reuse it somewhere? But I did change the bat inside zip of games like red alert and it worked fine...
