Image Field Problem

Hello,
I’ve installed Scriptcase 9.6.
Now when I setup an Image Field on Form, it produces a strange error on .apl file.
Around line 4260 scriptcase adds this strange code:

echo '"" @@ ’ . '$this->txt_image_;exit

That causes lots of PHP errors in the code because some command is not closed correctly:
Parse error: syntax error, unexpected ‘txt_image_’ (T_STRING), expecting ‘,’ or ‘;’ in /Applications/Scriptcase/v9-php73/wwwroot/scriptcase/app/APP_NAME//form_immagini_prodotti/form_immagini_prodotti_apl.php on line 4281

If I comment that line the problem is solved but on image click (lightbox)
the image is not found.

I cannot fix this since this file if autogenerated every time. I tried also to create a form application from scratch, but same problem.

How can I do?
Thank you
