[נפתר] Troubleshooting is safe?

Background of the issue:
I am using WPML and received instructions to use the Troubleshooting feature by selecting everything and clicking start. I understand the importance of making a backup beforehand, but I'm still wondering if this is safe and how much chance is there of something breaking? My site is קישור נסתר, and I have a store with ongoing orders.

Symptoms:
I described my problems here: https://wpml.org/forums/topic/when-i-edit-a-product-that-has-a-translation-edit-it-in-the-original-language-pl-sometimes-the-a/

I am still trying to solve them.

Questions:
Is using the Troubleshooting feature safe?
How much chance is there of something breaking when using Troubleshooting?
