When using the Builder to copy a structure including blocks that have NBT (such as Forestry Wood Piles, which use NBT to differentiate between species) it places them without any NBT data.

Using RFTools 1.10-5.53.

Thank you for taking the time to create this issue, as we're no longer supporting versions below 1.12, I'm going to go ahead and close it but if this bug seems to continue over to newer versions, please do report it again so we can investigate the issue further.
