I find I can reproduce the OP's observations, and the most recent advice
doesn't fix it (although it changes the symptoms):

From mintty/bash:

  639> cd /tmp
  641> ls -ld .
  drwxrwxr-x+ 1 ht None 0 Dec 13 19:55 ./
  640> getfacl .
  # file: .
  # owner: ht
  # group: None
  user::rwx
  group::rwx
  other:r-x
  default:user::rwx
  default:group::r-x
  default:other:r-x

  642> touch x3
  643> ls -l x3
  -rw-r--r-- 1 ht None 0 Dec 13 19:59 x3

Switch to CMD (not elevated):

  C:\Users\ht>cd ..\..\C64\tmp
  C:\C64\tmp>echo > x2
  C:\C64\tmp>

Back to mintty/bash:

  644> ls -l x2
  -rwxr-xr-x 1 ht None 13 Dec 13 20:00 x2*

OK, try the advice

  645> setfacl -bk .
  649> getfacl .
  # file: .
  # owner: ht
  # group: None
  user::rwx
  group::rwx
  other:r-x

  646> echo > y3
  647> ls -l y3
  -rw-r--r-- 1 ht None 1 Dec 13 20:01 y3

Over to CMD:

  C:\Users\ht>cd ..\..\C64\tmp
  C:\C64\tmp>echo > y2
  C:\C64\tmp>

And back to mintty/bash:

  648> ls -l y2
  -rwxrwx---+ 1 ht None 13 Dec 13 20:02 y2*
  650> ls -ld .
  drwxrwxr-x 1 ht None 0 Dec 13 20:02 ./
  652> setfacl -bk y2
  653> ls -l y2
  -rwx------ 1 ht None 13 Dec 13 20:02 y2*
