change in ftype is not being read, how can I make it be read or what is being read before it?

I have a file extension .vbsc which is associated with cscript and i'd like it associated with something else, even calc.exe I just want to be able to change the association but I don't seem to be able to. But I can for other extensions. Below is a demonstrartion.

In the demonstration, I use assoc and ftype to create an association for a file extension .ab5 and the demonstration shows that works. I then change the association so it brings up another program, the demonstration shows that works. I then try it with my problem extension, and it doesn't work. And it's not because my problem extension is 4 char long, there are many long extensions.

There is a second demonstration below this one which I describe where you scroll down to it. So it's reading something else before ftype.

C:Usersuser>assoc | grep -i vbsc
.vbsc=VBS_Cscr
C:Usersuser>assoc .ab5=AB5file
.ab5=AB5file
C:Usersuser>ftype AB5file=c:windowssystem32calc.exe
AB5file=c:windowssystem32calc.exe
C:Usersuser>echo asdf>a.ab5
C:Usersuser>a.ab5
C:Usersuser>rem the above brings up calculator
C:Usersuser>ftype AB5file=c:windowssystem32charmap.exe
AB5file=c:windowssystem32charmap.exe
C:Usersuser>a.ab5
C:Usersuser>rem the above things up charmap
C:Usersuser>abc.vbsc

C:Usersuser>assoc | find /i "vbs"
.vbs=VBSFile
.vbsc=VBS_Cscr
C:Usersuser>ftype | find /i "vbs"
VBSFile=%SystemRoot%System32WScript.exe "%1" %*
VBS_Cscr=c:windowssystem32calc.exe
C:Usersuser>

In this demonstration I delete the extension. It still associates with cscript.exe
