No changes to the instance (version, update, customisation) have been done.
There is no bloat in the question text, the source of the text is "For the following criteria..." (without the quotation marks).
Setting the survey as active or inactive does not change anything to the problem.
This sounds highly unlikely. If there have been no changes, nothing should change.
For something to change, there must be some form of change, either in the questionnaire, or the installation or the server.
Seeing that your version is 3.15.0+181008, which is now almost 4 years old and thus hasn't received any updates since 08/10/2018, no security updates, no bug fixes, etc. I think we can rule a change in the Limesurvey installation out. However, you really should update this "ancient" thing. In times of data protection laws like GDPR, LGPD, etc. all over the world, I don't think it is a good idea to collect data with a software that hasn't been updated for almost 4 years now. Especially as you seem to be collecting data in the healthcare sector, where the rules are even more rigid.
I also just imported your survey into my Limesurvey Version 3.28.8+220426 and in Fruity it looks just fine. So you should have a look if there has been changes made to your Fruity theme. If so, use an original Fruity as it comes out of the box and see if the problem persists. It shouldn't.
