Can't visualize heartbeat in Kibana 5.6

Elastic Stack Elasticsearch
1

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?
