indexterm issue

[Andrei Bondarenko]

In several DITA-topics I've defined some <indexterm> elements:

<indexterm>LEV1
   <indexterm>LEV2
      <indexterm>LEV3</indexterm>
   </indexterm>
</indexterm>

But sometimes, when saving a file, I get:

<indexterm start=";;;"></indexterm>

What am I doing wrong?

What version of FrameMaker are you using? Thanks.

I just tested this with FrameMaker 2022 (17.0.6) and am not seeing this. Are there any special characters in your indexterm elements?
