Warnings in ouput log

[simonbdbc]

Hello,

I have these warnings in my output log :
WARNING StudyModel::getInfo() study info not found: com.motivewave RENKO_TEST
WARNING StudyModel::getInfo() study info not found: com.mycompany GANN_HILO_RENKO

I have the impression that this is data that has remained in cache, these IDs and Studies no longer exist. How can I check or remove this ?

Thanks
