How to remove ghost tags left after regex F&R operation

Hi guys,

I have a bunch of segments where I've used regex F&R to remove .-€ from the end of a number and add at the start.

But some segments have formatting tag pairs in them (font colour and bold) and I'm left with ghost tags.

The target file saves correctly and I don't actually mind whether these numbers are bold or normal font. But it's messy.
Is there a way to batch restore ghost tags? Is there a better way to handle this? 

Many thanks and Happy NYE to everyone,
