A few apps answer file always selects MSSQL and not MySQL

There are 3 apps (phpBB, Joomla, Drupal) which allow you to choose the Database Server type upon deploying; either MSSQL or MySQL.

For these 3 apps, whenever I try to deploy using a parameters file, it always detects/chooses the server type of MSSQL even if we are using MySQL Parameter names.

Other apps are not having this problem, it seems specific to these 3 apps.

Example parameter names generated / used in the .app file:

phpBB w/ MSSQL:

AppPath[@]
SQL DatabaseServer[@]
SQL DatabaseName[@]
SQL DatabaseUserName[@]
SQL DatabaseUserPassword[@]
SQL DatabaseAdministrator[@]
SQL DatabaseAdministratorPassword[@]


phpBB w/ MySQL:

AppPath[@]
DbServer[@]
DbName[@]
DbUsername[@]
DbPassword[@]
DbAdminUsername[@]
DbAdminPassword[@]


Is anyone else able to duplicate this?
