File naming : No longer able to input a start number when custom naming file.

[Mike27775416tz8j]

Why is the start number grayed out when doing custom naming now??

I use the start number feature all the time and now I can't use it and need to rename manually with specific numbers. Awsome...Any way to fix this? Lightroom 12.1. MacOS Ventura 13.0.1.

I fitured it out, it need to be selected to Custom name -Sequence.....
