Reproduction steps:
1) Create a tag: testtag
Probably reproducible with any content, although I tested it only with wiki
2) Create a new WikiNode: testnode and delete the default Main node
3) Create a new wiki page and tag it with the previously created testtag
4) Create an Export
5) Start a different/new Liferay or start the same with another/empty database
6) Create there a tag with the same name: testtag
7) Import the LAR

Result:
