Problem in Conditional tag

Dear friends,

I am using conditional tag feature on one of my topics in robohelp and the topic is getting excluded from the output. However, the numbering in TOC doesn't change. For example,I have the following sections in my help file:

1.1 A

1.2 B

1.3 C

If I apply CT on 1.2 it is excluded from the output but the TOC appears as follows:

1.1 A

1.3 C

1.2 is removed but the numbering is still the same.

Can anyone help me in solving this problem. The numbering should also get modified in the TOC like:

1.1 A

1.2 C
