The Analysis Page on the Solr Admin Page does not work with Custom Analyzers. To be specific the Analyzer page does not display all of the tokens output by the custom analyzer if the tokens themselves don't have a KeywordAttribute added. It does not matter that the tokens are not keyword tokens, it is just that the Tokens need to have the KeywordAttribute (even if it evaluates to false).
I'm attaching the json output of the case of a text_en field (solr.Text fieldType) and the json output of the case of a field (mapped to custom fieldType).
The json generated for the custom fieldType (using a custom analyzer) while similar in all aspects to the json generated for text_en fieldType does not have KeywordAttribute set for the tokens (which seems valid).
JSON From the analysis page for the custom fieldType (custom analyzer)

The latter json does show up correctly in the analysis page whereas the former doesn't show up correctly.
Especially if the text involved in analysis involves StopWords.
