Broken: (3.1.0, as found on the splash screen)

Short description of error
In sample file, each character made by the curve exist in the collection named "texts".

At the geometry node, I'm trying to retrieve each character from the collection information in sequence.

But if I set the index to a number, the objects do not come out in order.

Please check the attached file data.

There should be an "F" after the "E". But, for some reason, "G" appears.

As the number of characters increases, the phenomenon that the index becomes strange frequently occurs.

Exact steps for others to reproduce the error
Change the integer connected to the instance index and compare it to the collection.
