UK date format DD/MM/YY in ODT template?

Hi Everyone
I have just started using Dolibarr and am loving it…
but…I am having trouble with the ODT template system.
I made a template which now works fine (after about a day of work…) and looks similar to the templates I have been using previously, BUT I just noticed that the dates are in US format MM-DD-YY and I need them to be in DD-MM-YY.
Is this a Dolibarr settings thing, an Open Office thing or what?? I can’t get anywhere with this - please HELP!!!
NB, I noted this was a specific bug-fix included in an upadte some time ago, and I am using the latest version 3.7, so it should be an option??

look inside, maybe what you need

it’s a lot to look through and I don’t know what I’m looking for
So far I have replaced the date variable with the built-in open office date field and that works OK (as I am converting to PDF, the date will remain static once converted)
