Size in columns table go crazy

Summary:

Hello,

Please, I need help with the following:

I have a master-detail with 2 tables.

I have noticed when rows in master do not fit in size (more than 4 records) , the columns size start to grow and the screen becomes unmanageable.

Moment 1.

Moment 2.

I have not seen anything weird in the data for master and detail business objects, just

Kind regards.

Juan
