After a fresh import I wasn't able to reproduce this error. How about others?

I'm installing a new instance and will check.

After starting a new instance, deleting file store, and deleting/reindexing solr the organism part and cell type were cleaned up alone with linger analyses ref #802
The issue was partly created when I ran vagrant destroy last week through the command line. The command did not completely destroy vagrant (Scott checked through the virtual box gui.) So, we destroyed it through the gui, which worked. Solr needs to be reindexed after running vagrant destroy, which I also did not do last week.

Tested with RFC dataset exhibiting this faulty behavior

Steps:

• Delete the dataset via admin interface
• Rebuild solrs index w/ ./manage.py rebuild_index --using=data_set_manager --batch-size=25
• Reimport the DataSet

Before:

After:

0s seen in the Type and Name filters are now gone.
The Steps mentioned above have successfully addressed this issue.

This is probably caused by the fact that Solr's index is not destroyed when running vagrant destroy. To avoid it: either delete the vm completely or rebuild / drop Solr's index.

@flekschas I agree, should we include it in the wiki somewhere?
