Incorrect view updates

create table t (p int, c int, v1 int, v2 int, primary key(p, c));
create materialized view mv as select p, c, v1 from t 
where p is not null and c is not null primary key (c, p);

insert into t (p, c, v1, v2) VALUES(1, 1, 1, 1) using ttl 5;
update t using ttl 1000 set v2 = 1 where p = 1 and c = 1;
delete v2 from t where p = 1 and c = 1;

// Wait 5 seconds
select * from mv;

c | p | v1
