Thank you for reporting.
For a record, this issue does not happen on Spoon (PDI CE 9.0), but happens on webSpoon (0.9.0.21).

I've noticed that the following error message appeared:

Ignored reentrant call while viewer is busy. This is only logged once per viewer instance, but similar calls will still be ignored.

Glad for your fast action in this issue.
Where did you get this erro message? Which log file?

[HiromuHota]

You can see this log by docker logs -f webspoon or directly look at /usr/local/tomcat/logs/catalina.2020-XX-XX.log.

[HiromuHota]

I confirmed that this issue was reproducible on 8.2 and 8.3. Not confirmed, but maybe older versions too.
