During the 'Rebuilding Indices....' phase of a repotools-rm.bat -import command on a RM tar file I exported from a server running RM 7.0.2 and was reimporting in to a server running RM 7.0.2 the RM import log file shows the following (only the first issue is shown):

2021-03-28 18:46:24,805 Importing deferred items...
2021-03-28 18:46:25,320 Finished importing deferred items.

    ...(lots more)...

Does anyone know of a workaround for this issue?  (Note that I successfully exported/imported 7.0.2 tar files for two other servers with different instances of the 7.0.2 apps but both of those did include RM tar files (though both were much much smaller in size).

Thank you in advance!
