Well, it would be easier if you supplied the script in question, but
let's see what happens when you C&P this one to an exxecutable file and
call it.
#!/bin/sh
export ONETIME=1
export TEATIME=2
export THREETIME="three"
export -p
echo $ONETIME
echo ${TEATIME} TEATIME
echo ${THREETIME}
As usual, the hashbang had better be the first two characters in the
script file.
Here is my output for it.

our exported variables are unset, as it should be.
If you get similar output, all is well. What will never happen is that
the exported variables get back to a calling routine They only get
passed to called routines. You need to be a little more clever to pass
them back (see functions), or you need to evaluate the ENV variable and
append your exports to that file, then do an exec to terminate the
current shell process and call the oiginal caller with a new ENV.
