I did a test and found out that a drop down list in the adobe form is only displaying 1 entry when the actual entries retrieved are more than 255 items.
Looks like the drop down list is only able to contain 225 items, if it has more than 225 items then it will shows only 1 entry for selection.
Please advice if there is any solution to fix this?
