strange trigger in the triggers window

[GArmao]

if I go to the Monitoring->Triggers among all the problematic triggers I have, there is one that I think shouldn't be there, I attached a screenshot.
The "Never" link has an url which is this: http://zabbix/zabbix/events.php?trig...ac08a444aaeb59
I then went directly on the mysql database to find out which trigger had that trigger id, and that's what I got:
mysql> select * from triggers where triggerid=100100000012201;
+-----------------+--------------------------+--------------------------------------------+-----+--------+-------+----------+------------+-----------+----------+-------+------------+------+
| triggerid | expression | description | url | status | value | priority | lastchange | dep_level | comments | error | templateid | type |
+-----------------+--------------------------+--------------------------------------------+-----+--------+-------+----------+------------+-----------+----------+-------+------------+------+
| 100100000012201 | {100100000011201}>150000 | icmpOutRedirects on {HOSTNAME} is too High | | 0 | 1 | 3 | 0 | 0 | | | 0 | 0 |
+-----------------+--------------------------+--------------------------------------------+-----+--------+-------+----------+------------+-----------+----------+-------+------------+------+
1 row in set (0.00 sec)

Then I inspected which function was associated to the trigger:
mysql> select * from functions where triggerid=100100000012201;
+-----------------+-----------------+-----------------+-----------+----------+-----------+
| functionid | itemid | triggerid | lastvalue | function | parameter |
+-----------------+-----------------+-----------------+-----------+----------+-----------+
| 100100000011201 | 100100000017201 | 100100000012201 | NULL | delta | 0 |
+-----------------+-----------------+-----------------+-----------+----------+-----------+

and then the associated item:
mysql> select * from items where itemid=100100000017201;
Empty set (0.00 sec)

No item is associated with this trigger, why is it showing up?

Edit: totally forgot to mention that I'm using Zabbix 1.8.3 recently upgraded from 1.8.2 but I can't remember if this item was showing before

thanks, I tried it but I got this error:

ERROR: Zabbix has received an incorrect request

* Critical error. Field [groupid] is not integer
* Critical error. Field [hostid] is not integer

this is the url showing on the url bar:

http://zabbix/zabbix/triggers.php?delete=1&form=update&groupid=&hostid=&triggerid=100100000012201&sid=efac08a444aaeb59

I had to remove the groupid=&hostid=& part from the url and the trigger got deleted.

oh, it worked without additional modifications before - thanks for the update
