[Acrobat Reader] the cursor moves in the end of text box of sticker note when I insert white space in Korean Input Mode

I often use the sticker note in Acrobat Reader but I have a inconvenience the Keyboard input cursor moves in the end of text box of sticker note when I insert white space in Korean Input Mode.

There is no problem when I use English Input Mode. Only using Korean Input Mode and pressing the space bar make the keyboard cursor move in the end of the sticker note.

Until I press space bar, I can input Korean character where I do. But just when I press space bar, the character I am inputting and the space are moved to the end of the sticker note and the cursor is also moved there.

I experienced this situation on the other PC too. So I think this is the problem of Adobe Acrobat reader.

How can I resolve this situation?

Thanks in advance.
