Using latest stable version (1.1.4.5), when setting bottom layers to >9 in slicing settings give a proportional ‘empty layers’ relating to the number of layers >9. 
Have checked in slicing viewer and indeed, they are missing.
I’m not sure why this is happening but for my project I needed 75 layers to be harder to strengthen a very fine support design.
Hello
Just an idea:
Do you have XY- offset or Z-Bleed correction activated?
I have the feeling that the layers are just missing because they are too small and then
not shown due to a shrinkage or any other correction-operation.
Best regards, Chris
Hi,
It looks from your first screenshot you are not using z-bleed or any shrinkage correction. So that can’t be it.
I tried it with a bunny model and 72 bottom layers; could not replicate the issue.
That leads me to suspect it’s model related.
The geometry slicing operation is unrelated to bottom layers; only if you have different layer heights different things come into play; but you don’t have that i think?
Have you repaired your file?
Have you tried another random file is the problem is the same?
kind regards

On second thought;
i think it can very well be what Chris mentions; the bottom xy offset removing the entire object if it gets to thin…

Hi Chris & Elco,
Apologies for not getting back here any sooner - I have just taken off my X/Y compensation and sure enough the issues is resolved 
It now seems obvious! But thank you for being so swift and diligent in answering my query. 
Appreciate the support, one of the reasons why this is must-have slicing software!
Best regards
Frankie
