CustomSettings override selection of Film Simulation setting

[kb_stabs]

For my X100VI, I have Custom Settings/Recipes in all 7 slots.  If, for a change, I want to shoot with one of the stock film simulations (ie. with no changes to any of that film simultation's settings) I find that the settings of the last-used Custom Setting are carried over to the selected film simulation.  Surely this isn't the expected behaviour.  Am I missing a step here?

A film simulation is just one part of the recipe.

If you have a recipe selected and change the film simulation none of the other settings within that recipe will change.

It would be the same as Grain Effect for example - you could select a recipe and change Grain Effect - nothing else within the recipe with change.

You can change the recipe back to "nothing selected" before you change film simulation and the last used recipe settings won't be carried over.

Many thanks Greybeard for responding .  I understand what you said perfectly .  Perhaps I didn't make my question clear enough.  It seems to me that it should be possible to select one of the default film simulations with their default (zero) settings with a single action, even though all 7 custom settings slots are filled.  As you say, changing the film simulation in any one of the custom slots does not effect any of the other custom settings for that slot. The only way I see to be able to have custom recipes AND be able to select default film simulations is to have one custom slot for a chosen film simulation but with all settings unchanged at their zero values.  Then, different film simulations can be simply selected in that one custom slot.

According to Tony Phillips, who wrote “The Complete Guide to the Fuji X100VI”,  (I’m working through the book as we speak) he sets up C1 as the default camera setting and assigns the custom menu to a function button, so that with a push of a button you can scroll through and select C1-C7 quickly.

As far as I am aware, this is the only way to quickly get back to default camera settings.

The custom settings have been a real frustration over the years, as they don’t save all camera settings, which I find really strange.  I’m sure there must be a valid reason for this and if anyone knows, please tell me.  An example is when I want to save a setting for using studio flash, I need the “preview white balance” to be saved to a custom setting but not to affect all my other custom settings but alas, I can’t.  Some settings have to be changed manually.
