Conflicts in pasted tags

[Allroads]

Hello,

When I use the icon for CTRL SHIFT V,

1. I have often the problem that I get not the expected tags from the clipboard.

It sometimes I set ford to it, and the next road I want to give with icon only highway tag, but then there is ford=yes from the clipboard, is there a learning process to give me other presumed tags in the clipboard. (two pics)

2. Popup Conflicts in pasted tags.

What annoying is that I can not get none for a choice, this ford is set also, form a clipboard.
But when I choose the right tags. The apply button does not light up.
When I choose to go not further and click the red cross, expecting to delete all, all tags are set. (two pics)
