Changing to marker gene heat map shows cell types

[ke4]

Steps to reproduce:

1. Go to Browse experiments tab and select for example Transcriptional programs of circuit assembly in the Drosophila visual system
2. Switch to Marker Genes tab
3. Cell type heat map appears on the screen

Expected result: The default value is shown under the Number of clusters dropdown, preceded by k =

Actual result: The Inferred cell type metadata value is shown under the Number of clusters dropdown, preceded by k = (see screenshot below)

If you click on the Number of clusters dropdown the Inferred cell type value isn’t available.
