Empty lines or text breaks with "include content /a shared block"

[Silke Baumgarten]

Hello everybody!
in our confluence environment we work mainly with "shared blocks" ( from the include content plugin). Everything works great and we are very satisfied.
Unfortunately, we sometimes find empty lines or text breaks where we didn't set any.
I can't explain why this is the case. At the moment I solve the problem by searching for a working shared block and then copying the information from the broken shared block into it. But this is very cumbersome in the long run.
Has anyone else found a solution for the problem yet or am I the only one who has the problem?
