Apache directory section options for Multiple PHP per directory set to +Indexes instead of -Indexes.

Config:
OS: Centos 7.5
Default php: 5.4.18
Second php: 7.1.8 from SCL

Steps to reproduce:
1. Add multiple PHP to any directory in virtualmin.

Result:
< Directory > section for specified multiple PHP directory in httpd.conf is given the option +Indexes

Expected result:
< Directory > section for specified multiple PHP directory in httpd.conf is given the option -Indexes

When adding multiple PHP support from a directory in virtualmin the Options in < Directory > entry in httpd.conf is written with +Indexes allowing directory index display instead of -Indexes preventing it like most other virtualmin generated Options in < Directory > sections.
