Hi Molly,

This is the full XML for that table in the sample schema:
<tables xmlns="http://labkey.org/data/xml">

<table tableName="RNAseq_projects" tableDbType="NOT_IN_DB"> <columns> <column columnName="Description"> <isHidden>false</isHidden> <shownInInsertView>true</shownInInsertView> <shownInUpdateView>true</shownInUpdateView> <shownInDetailsView>true</shownInDetailsView> </column> </columns> </table> </tables>

If I remove the bit i sent earlier it un-ticks the boxes on the advanced settings.
I also tried a different sample table in the same folder and it's doing the same thing.

The exp.materials table has:
<tables xmlns="http://labkey.org/data/xml">

<table tableName="RNAseq_projects" tableDbType="NOT_IN_DB"> <columns> </columns> </table> </tables>

I've just checked in dev on a different table (the RNASeq ones don't exist in dev) and it's working fine. Selected description for the default fields and it's appeared in the insert form and ticked all the boxes in the advanced settings. However, it didn't add the XML:
<tables xmlns="http://labkey.org/data/xml">

<table tableName="section_to_sample_and_target" tableDbType="NOT_IN_DB"> <columns> </columns> </table> </tables>

I've then tried making a new sample table in prod and it works fine.... I also tried a different sample table in a different folder and it's fine! So it's just these two sample tables in this specific sub folder.... I might need to re-make them :(

Best,
Katy
