Looks like it is somehow linked to either Relevance or to the HTML generation script. The questions shown in the screenshot are both conditioned by a relevance formula linked to some checkboxes earlier on the page. However, the difference is that [ceoID] is by default with relevance=1, while the [cooID] with relevance=0 at page load (i.e. hidden until the user clicks the relevant check ox). When I uncheck the box for the [ceoID] question (making its relevance=0), it disappears (as expected). When I check it back (relevance=1), it appears, but now it's "error" class with red text and the "!" symbol. So somehow the formatting depends on when the question is shown: at page load, or afterwards.

I see this error sometimes, hard to find where/how to reproduce exactly. And sems it's a new bugh.

Can you try to make the smallest and simple survey for testing purpose and attach here ?

I've uploaded the survey (tip_style_bug.lss). I think the bug depends on hide/show logic in the relevance engine. The survey shows two file upload questions, which are ok at first, but as soon as you uncheck the relevance checkbox and check it back, the style changes. so maybe that's why it was hard to catch.

Yes, seems to be this , i see it too with "relevance question" , thanks :).

My pleasure.

I suspect there is a similar bug with other tips. I've seen it at least once with Numeric only tip, but have not tested. I imagine fixing this will fix it everywhere since it's style-specific (probably).

This bug has been resolved in 2.5
