Outer Join not working

I have data in a CSV called 25_million_Linie_Rule.csv (example below)

host,source,count
"INTERFACES_BUILD","/hp547srv1/apps/INTERFACES_BUILD/logs/traces/mxtiming_956675_hp547srv.fr.murex.com_**1254**.log",31436700

I also have data in real time.
If the data in rela time is the same as the .csv i don'twant to report it . So an outer join is needed, but i cant get it to work.

| tstats count where index="mlc_live" OR index="mxtiming_live" by host source 
| dedup source 
| sort 0 - count 
| head 10 
| where count > 25000000 
| table host source count 
| join type=outer source  
    [| inputlookup 25_million_Linie_Rule.csv  ]

OUTPUT is below (However i get a line i already have in the csv, i should only get one line, the new line not the one i have in the .csv )

host    source  count
INTERFACES_BUILD    /hp547srv1/apps/INTERFACES_BUILD/logs/traces/mxtiming_956675_hp547srv.fr.murex.com_**1254**.log 31436700
INTERFACES_BUILD    /hp547srv1/apps/INTERFACES_BUILD/logs/traces/mxtiming_956678_hp547srv.fr.murex.com_**1992**.log 26617140

Any help would be great

I think the join is working as intended. Because the same event that lives in your 25_million_Linie_Rule.csv also would be found in your real-time main search. Doing the join should not remove events found in your main search that match those events in your 25_million_Linie_Rule.csv as I think you want.
