When using Basic filters it adds them as "AND" to the query. So the fields would both need to match in order for a user to display. If I understand correctly you're wanting an "OR" scenario as in if Field A = 1 or Field B = 2 then display the user. If this is correct please try the below "Advanced" filter.
Code:
( ( ue.`cb_fieldname1` = 'value1' ) OR ( ue.`cb_fieldname2` = 'value2' ) )
With the above replaced cb_fieldname1 and cb_fieldname2 with the actual names of your fields (e.g. cb_text, avatar, user_id, etc..). You'll also need to replace value1 and value2 respectively.
