Hello.

First, I am brand new to Easticsearch, Kibana, logstash. I am working with it for a few days now and now I have to following problem.  
Please feel free to point out my mistakes and guide me in the right direction to accomplish my goals.

I added multiple data sources (database tables) with different data formats from my two SQL - servers into one index pattern.

One is a production-style table, where user behavior is stored.  
The second one is an error table where error messages and events are stored.  
Finally there is a table were additional log data is stored.

All three table have a different table structure.

Now, I imported all the data (6.5 million docs) with logstash into elasticsearch. If I run /_cat/indices I can see the it.  
I indexed them mfa\_XXX, mfa\_YYY and mfa\_ZZZ.  
The index pattern I used in kibana was "mfa_\*". I created it after the first import, to check if everything was ok, and I saw my data. Then after the last (ZZZ) import I updated the index to see all the fields. All the field in the index pattern list are there.

Now my problem:  
I imported mfa\_xxx, first, then YYY and this afternoon ZZZ.  
Now I can't access the data from XXX and YYY not longer, Discover only shows the ZZZ data. If I try to visualize all the other data, it just says "not available". If I search for it, it isnt there anymore.  
The pattern fields are still there, but grayed out.

What happened? What did I do wrong?  
How to fix this, to be able to analyze all the data together, what my job is.

I am using:  
elasticsearch 5.5.1  
logstash 5.5.1  
Kibana 5.5.1  
all on windows 7
