Query "starts with" doesn't work on some fields with same type

I've got field type called "text_lcase" (you can find details below)

<fieldType name="text_lcase" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/> <!-- lowercases everything -->
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>

So I use this field type for name and email. Before email field had type string. I reindexed solr, for some reasons it worked fine for a while but stopped working again.
Example of queries:
name:John* (works on all fields have got this value or if it starts with this value)
email:example@hotmail.com* ( doesn't work)
email:example@hotmail.com ( works)
email:example@hotmail* (doesn't work)
