Question: remove element from listlist and member question

L:=[[name,4,3,6,5],[3,5,name],[3,6,1,2,9,8]]   I want to remove name from the listlist or all 3's for example

I've tried

remove(has,L,3) which removes the entire sublists containing 3 so I tried

map(remove,`=`,L,3) but that doesn't work I thought since remove(`=`,L,3) worked on a flatlist that using map would work on the listlist or even map2(map,remove,`=`,L,3).  I can't figure it out.

And how do you use member on L?  I end up with false on all the combinations using map map2 map[3] I can think of.
