Side note first, this IS a forum - not a blog - those are 2 different things.
Usually in a forum one would keep the issue at hand within a single thread, and then add/update as relevant.
Just a hint, you implied you didn't know ;-)
This is sadly a fairly common issue, also seen on the MiniBrute synth among other. Without having seen it first hand, i've gathered it's about the glue used by Arturia sometimes not binding properly. Most people will usually just do as you did and glue it back themselves. If using a good glue this is likely to last longer than the keyboard itself. And if you're comfortable doing this yourself, it shouldn't be a major issue. Atleast it sounds like you're using a reasonable technique.
In the future, if you're for some reason uncomfortable with the product, it does actually constitute a defect, and would in most cases make you eligible for returning it, either for a professional fix, swap for a new unit or a full refund. Though not so with the ones you've glued back yourself.
Hope everything turns out alright for you.
