Token Elevation set by Included Macro is lost for some tokens on refresh

[Shuggaloaf]

To recreate:
-Select a group of tokens
-Set their elevation
-All selected tokens now show the entered elevation
-Click F5 to refresh the game
-Some tokens will no longer have a set elevation. Some will retain it.

I'm guessing a tweak is needed to the macro but this is beyond my abilities.

Details:
Foundry 0.8.9
Wall Height 3.6.0.1
All other mods disabled except libWrapper and Advanced Macros
