It appears you can’t have an ID in a Custom Component that starts with the letters **preview** , i.e. **previewLoggedIn** as an ID fails with the message:

![CleanShot 2024-08-26 at 10.25.13](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/e/6/e6b322f8b6bf32efbf99f0e2d3ec8efcd9dc2b65.png)

I assume this is because **preview** is an Elements system ID and the parsing is stopping as soon as it finds a match on an Elements system ID?

Changing the ID to **pvLoggedIn** resolves the issue.

Not sure if this a bug or feature, but would prefer it to be a bug?

Oh good find! That is indeed a bug, I’ll add it to the list 👍
