So your CSV looks like this?  
somedata;3-Mar-18  
otherdata;Mar-18  
moredata;3-Mar-18

Then your rdate result at the end should be right and the tag is justified, isn't it? I mean, one of the two filters would have to fail because either the first one is successful and the second is trying to parse a date time object which it cannot parse or the first one doesn't find the right date format and the second one gets it right?  
When I try out your configuration, I get "rdate" =\> 2018-03-02T23:00:00.000Z and "rdate" =\> 2018-02-28T23:00:00.000Z. (March was UTC+1 for where I live, so I guess that makes sense).

If you do not want to get that tag, you will probably have to check the date format with a regex first.  
if([rdate] =~ /^\d{1,2}-[a-zA-Z]{3}-\d{2}$/) {  
...  
}

According to [https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html#plugins-filters-date-match](https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html#plugins-filters-date-match), you should be able to combine the two date filters into one like this:

```
date {
	match => ["rdate", "d-MMM-yy", "MMM-yy"]
	target => "rdate"
}

```

This will then perform the conversion on either format that it finds the field in.
