screen painter space between two element in one line

Hi Experts,

i am developing a RF program with screens of size 16linesX20columns. limited space should be used . But when i create more than one element in one line , one space is always present between two elements,and the space can not be deleted or overlaped. because of this, elements can not get enought columns.

i am sure that elements can be adjacent without space in the past time. i am not sure space appear after what changes was done by me...

can you please give some suggestion if you also have the same issue.
