Font changing in PC-generated reports/pdfs

Hi,

Until recently all pdfs/reports generated from the system or programs on the system were in Arial.

Now they appear in Bahnschrift ?

Can anyone help to get back to arial please, as hard to read with that font.

Not sure what has caused this, possibly a windows update?

Adobe is up to date, as is Microsoft 10.

Have ticked the 'use local fonts' in page display - well was already ticked.

Thanks for any help !!
