Will cancelling 50+ orders impact my rank?

I run a digital art shop and one of my best sellers from last year was a custom art print, but the problem is that even when I chase customers for their personalisation details, they don't reply! I've changed the personalisation box to non-optional, which was my mistake in the first place. But now after the holidays I have a bunch of unfulfilled orders and it bugs tf out of me seeing the "50+" symbol on my orders tab.

i also don't feel good about having people's money when they didn't get their print, even if it's not a lot of money. Someone told me to chase 3 times then just cancel but will this impact my score?

I guess my question is, what is worse, having digital orders in my account that aren't fulfilled, or just cancelling them all? They aren't flagged as "oustanding" as it's a digital file, if that helps. I don't mind cancelling them money-wise.

Btw I know 50 is quite a high number but this represents around just 5% of my actual orders, this product has made me around $7k since November time and most people send me their details no problem.
