Steps to reproduce:

1. Export Map that includes icons with trigger to JSON
2. Go to maps / import
3. Select file, start import

Result:
The frontend endlessly runs, does not complete.
Tried with different maps.

Expected:
Proper import with existing triggers (no other changes)

Hand-edited the JSON to see what part makes the import fail.
Turns out that i its ithe "selements" section.
There I have elements of element type 2 that look like follows:

"elements": [
   

Unknown macro: {         "description"}

,

That is an export from 6.0.0
Strange enough there is no reference to the name of this trigger.
Only description.

"rtp.count" is a user expression that is defined in the agent.

Any ideas how to fix this?
Still have the JSON, map was deleted and I would need to recover it.
