I just ran into this problem myself and found the solution.
On your Solr Server, edit the solrconfig.xml for the index you are using. It is found in the conf folder of your index.
Find the requesthandler you are using, for instance "/select", and add <str name="facet.limit">-1</str>.
Be aware that you have to do this for each index that you want to update.
For me it looks like this after the fix.
<requestHandler name="/select" class="solr.SearchHandler">
<!-- default values for query parameters can be specified, these
will be overridden by parameters in the request
