Question about Swiss Franc (6S) tick size

Per the CME website: https://www.cmegroup.com/markets/fx/g10/swiss-franc.contractSpecs.html

It states that Swiss Franc(6S) tick size is 0.00005 CHF increment = $6.25
(5 digits after the decimal point).

In SierraChart, the price scale is in increments of 0.0001 (4 digits after the decimal), with a tick size value specified in Symbol Settings of $12.5

I am not entirely sure that this is an "problem", but I am trying to understand why this is the case. I cannot seem find any explanation for this anywhere. It may be related to some "special half tick" situation, but I am not sure as I have never heard of this before.

This article seems to suggest that the tick size was changed in 2022...

But perhaps it was not updated in SierraChart?

We see that this has been updated for some services, but not for Rithmic specifically. You will need to change these symbol settings on your system to reflect this. Refer to the following:
Global Symbol Settings: Instructions

You will want to change the following to be what is specified here:
- Price Display Format: 0.00001
- Tick Size: 0.00005
- Currency Value per Tick: 6.25
