Pg 3 Multitext attributes causing issue to the next fields when not filled in

 Hi, We are using Agile 9.3 . I've created some Multi-Text attributes on Pg2 and Pg3 of Changes class, When any of these fileds are skipped to go to the next field , the screen flickers and behaves weird, doesn't allow you to enter the next field leaving this field blank ,even coming back to fill in this space also behaves weird . The next character you type in doesn't go to the next field or where the curser is placed, but anywhere else on the screen randomly,it picks the place.

Did anyone experience similar issues? Any advice or help is highly appreciated.
