Only one attachment at a time after upgrade from ver.4.13 to ver.6.5.3

[nolobolo73]

Dear Community,
I have just succesfully upgraded from version 4.13 to version 6.5.3
I am testing the new version, and I noticed that when I create, or update, or put a note into a ticket, toghether with attachments, only one attachment will be uploaded. In other words, I can choose more then one attachment, but after the process is accomplished the new ticket created or the new note created will be presented with just one attachment on it, just the first selected, all the other attachments will not be uploaded or show in the attachment area.


Is this behavior normal or, if is not, any advice how to fix it?


thank you for the advices and support
regards,
