*This is specific to V1.8.1 onwards.*

<u>**Symptom:**</u>

My Holder Type library has a value of 'zSYSTEM VALUE - DO NOT USE or DELETE'.

<u>**Cause:**</u>

This was implemented in V1.8.1.

Two tabs of in the Leases module (Land Tenure and Parties) share a single table in the database, and the application uses this library value to determine which tab the data sits in.  Little did we know in V1.8.0 that we had unwittingly made this visible to Users.  Therefore in V1.8.1 we changed the description so that you wouldn't use it.  This is a temporary patch.

What are we going to be doing?  Some very amazing things to the Parties and Land Tenure tabs to enhance how they work - which will make this issue redundant.

<u>**Solution:**</u>

Bear with us - it will be resolved in a future release.
