Hi all, I made an upgrade to 5.6 from 5.4, now I noticed that some dashboards do not work. Everytime I select a dashboard, an error occurs with the content "Set fielddata=true or alternatively use keywords".

Now I've checked my index which doesn't work and this is the output:

{  
"metricbeat-gastro-2018.02.20": {  
"aliases": {},  
"mappings": {  
"metricsets": {  
"properties": {  
"@timestamp": {  
"type": "date"  
},  
"beat": {  
"properties": {  
"hostname": {  
"type": "text",  
"fields": {  
"keyword": {  
"type": "keyword",  
"ignore\_above": 256  
}  
}  
},  
"name": {  
"type": "text",  
"fields": {  
"keyword": {  
"type": "keyword",  
"ignore\_above": 256  
}  
}

For me it looks like there are already keywords in use. So why does my dashboard not work? What could be the problem? Any solutions?
