Well, the wrong years must have come from somewhere.
It came from WoS internal file "maindb.dat" line 9905:

WoS didn't store re-release dates,
Wos stored re-release dates, but didn't display them.
When ZXDB started, it imported 100% of WoS content, even the part that wasn't displayed.

but the earliest copy of zxdb I have (17/5/2017) is full of incorrect ones.
Sure, there are still lots of incorrect information to be fixed. That's no surprise, considering that old WoS was a huge database and it's not easy to collect reliable information about titles released decades ago.
If you can download the incremental files mentioned in
this post, then run the first 6 files only, you will obtain the oldest version of ZXDB from when it started. It contains all the information imported from old WoS, and some "semi-automatic" bugfixes I embedded into the import procedure (that's about 101 Mb of SQL).
The remaining incremental scripts contain every change we made afterwards in ZXDB. What we have been doing for the last 3 years was fixing wrong information, adding missing data, cataloging MIAs and new titles (that's another 45 Mb of SQL and increasing).

Is it incorrect WoS data that wasn't displayed, an error in the conversion?
Incorrect WoS data that wasn't displayed.

There's no documentation to explain it!
The ZXDB overview is documented
here. More detailed information about ZXDB has been explained in hundreds of posts, most of them
here,
here,
here. And if you are interested in even more detail, then every single change ever made in ZXDB has been stored as commented scripts
here.
