loop multiple file with only 1st file being read - linux

Question

So I have a that works as it going to mulitple directories then within these directories takes multiple fields from files and store it in a .txt files.
There are two loop, the first one that loops through all the folder
the second one that loops through all the files.
The problem I encounter is in the second loops that it read only the first file in the folder and then it moves on to the next folder and ignore all other files in the folder.
archive=/imdata/archive
inventory_archive=/imdata/a/shares/b/inventory/c
ls $archive | while read p; do
echo "Project: $p"
mkdir -v $inventory_archive/$p
dir=$inventory_archive/$p
ls -1 $archive/$p/d001 | while read s; do
echo "Searching Session: $s ..."
find $archive/$p/d001/$s -type f -iname "*.txt" | while read f; do
echo "FILE: $f"
study=`/home/me/program/bin/script $f | grep -m1 "field1" | cut -d "[" -f2 | cut -d "]" -f1`
echo "SID: $study"
if [ ! -d "$dir/$study" ]; then
mkdir -v $dir/$study
fi
studydir=$dir/$study
series=`/home/me/program/bin/script $f | grep -m1 "field2" | cut -d "[" -f2 | cut -d "]" -f1`
echo "SID_2: $series"
if [ ! -a "$studydir/$series.txt" ]; then
touch $studydir/$series.txt
fi
sop=`/home/me/program/bin/script $f | grep -m1 "field3" | cut -d "[" -f2 | cut -d "]" -f1`
echo "SID_3: $sop"
grep -qsF $sop $studydir/$series.txt || echo $sop >> $studydir/$series.txt
