As shown in the figure, No. 101 (purple arrow) is in the opposite direction to No. 102. At this time, 101.jpg, which was newly saved after correcting the direction (rightmost picture), has an arrow pointing upward. However, whether I turn my computer off and on, create a new folder, or delete all my photos and move them back, the arrow always points in the downward direction before editing. What could be the problem?

function BtnOpen1ButtonPushed(app, event)

[app.filename1, user_canceled] = imgetfile('InitialPath', app.ROOT_PATH );

if user_canceled == true, return; end

[app.ROOT_PATH, name, ext] = fileparts(app.filename1);

app.Fn1.Value = app.filename1;

app.img1 = imread( app.filename1 );

image(app.UIAxes1, app.img1)

axis(app.UIAxes1, 'tight')

app.UIAxes1.Title.String = name;

nLen = length(name);

fmtspec = sprintf('%%0%dd', nLen);

name2 = sprintf(fmtspec, str2double(name) + 1 );
