I did a few more tests to try to isolate the Explorer bug and it seems
to be limited to Esignal data and it looks like it's coming from the
data on demand cache, or the downloader is creating the error. Also
sometimes the data symbols file doesn't clear itself properly in the
turbo feed data manager.
Check your explorations and make sure it doesn't happen with Reuters
data.
