Thanks for your quick reply!
Unfortunately I can not provide you with a link since the gallery I am talking about is installed within a password protected website (customer portal).
However, please find here 3 screenshots:
1st of the plugin backend, what I typed in:

2nd of the gallery preview – everything looks fine – “applicator” written in lower cases:

3rd of the live view after refreshing – “applicator” in capitals:

We have different galleries on that page and for some of them the captions work properly, for others they don’t.
Do you need any further info, such as code, size of the images etc?
