Change default level text plugin short descr shortcode not working for me

Hi there,

https://www.paidmembershipspro.com/add-ons/pmpro-custom-level-cost-text/

Thanks for this great plugin to enhance the main plugin by allowing you to customise the text – it would be great if there could be an option to lose the capitalisation though, eg on Free or Month, in the phrase that renders when you use the shortcode, as follows:

The price for subscription is?Free?and then?€6.00/Month

The Free wouldn’t be capitalised alone, when the rest of the sentence isn’t, it would be incorrect. I realise you can swap out for a number but this isn’t appropriate for our use case it’d look weird for us to say ￡0.00 here – also the available option showing in admin is a two decimal place number eg 4.00.

Re the word Month it would be incorrect for us to display ‘month’ as capitalised due to it’s position in the sentence and the fact that nothing else is capitalised (except the Free).

I would be grateful if could point me towards editing these outcomes to all lower case with a function or template for us in child theme? As I’d love to use your fantastic plugin.

Additionally it seems for me at least, that the short option shortcode !!short_cost_text!! just renders with the same outcome as the default !!default_cost_text!!, has that arisen before?

Kind thanks ??
