Civil Labeler - Have to close Civil Labeler when going from file to file or drawing model to model

ORD  2021 R2.  When using the civil labeler.  We have to close the civil labeler before going to a new file or model to be able to use it in the new file or model.  Otherwise it locks up ORD and have to close down and open the file again.  Anybody else coming across this issue?  It's really annoying when going through multiple sheets and labeling R/W points or flowlines on pipes and culverts on cross sections.  To have to close the labeler then open it up again.  

Thank you,
