[V7.0] Not able to use fields filtered through 'Transformation' in 'Data Link'

I used ‘Filter By Name’ to hide some of the columns. Then, later when i tried using those hidden columns in data link, it is not visible.

For eg., i have two columns ‘name’ and ‘link_1’. I need to create a table with ‘name’ as data link pointing to ‘link_1’. So, i selected both the columns through mysql query and removed ‘link_1’ through ‘Filter By Name’. Then, later when i tried to create a data link for ‘name’ field, then, ‘link_1’ (${__data.fields[link_1]}) wasn’t visible. If i remove the filter, then it is visible. This is a common feature that requires fix (or) am i missing something?
