Roll20AM: Adding Roll20AM call to spell description interferes with spell slot decrement

Hello, I added a Roll20AM call to a clap of thunder sound to the paladin's Thunderous Smite spell. The sound plays fine, but now the spell slot does not decrement.  How do I fix this?   Here is the screen shot of the spell in the 5e OGL sheet:

That trick of adding the }} followed by linefeed and the macro was a hack based on an older version of the sheet. The roll template fields are called in a different order now, and the trick no longer works properly. My workaround is to put an API button in the field: [Play sound](!roll20 am audio,nomenu,play|ThunderCrash) It requires an extra click, but spells operate correctly.

Thanks Keith!
