Suffix / prefix issue + bug

Hello
Great plugin you have ! Been playing with it but i have 2 issues.
– Suffix and prefix do not display (i’m trying to input €)
– when i try to changer value of thousand separator i typed 1 instead o f. and everything froze…I had to login again in adlin and delete the template. No worries if i take my gloves off and type . instead of a figure !
sincerely
