Bi Reports Does not Show LOV Correctly

Content

Dear , 

I created a user defined lov in (Manage List of Values Sources) and then defined into my reports . Reports run correctly with lov but issue is lov filed is too long. And i cant find why its too long. Its impact on our users they cant run report correctly because of this issue. I also attached the picture in which you can see that when reports run LOV text field is too long. i want to resize it. 

Note: Others 2 lov field show correctly but user defined lov issue occur.  if we select predefined options its size is correct but when we select user defined options its size is too long. and we need user defined option.
