error message from xpose

I know this is a NONMEM list server, but, need help with xpose, hope you'll indulge me. Moving to the latest xpose (from xpose4). I ran a model (using PSN, execute), model file called run001.mod, the $TABLE records are: $TABLE ID TIME TAD IPRED IWRES NOPRINT ONEHEADER FILE=sdtab001 $TABLE ID K S2 KA CL ETA1 ETA2 ETA3 NOPRINT NOAPPEND ONEHEADER FILE=patab001 $TABLE ID STDY SEXN RACEN XXXXX XXXXXX NOPRINT NOAPPEND ONEHEADER FILE=catab001 $TABLE ID AGE XXXXX XXXXX XXXX XXXXX NOPRINT NOAPPEND ONEHEADER FILE=cotab001 $TABLE ID TIME DV EVID CWRES IWRES XXXX IPRED NOPRINT NOAPPEND ONEHEADER FILE=cwtab001 I'm trying to load the data in to xpose, with command: xpdb <- xpose::xpose_data(runno = '001') getting this ouput: Looking for nonmem output tables. Reading: sdtab001, patab001, catab001, cotab001, cwtab001 [$prob no.1] Looking for nonmem output files Reading: run001.ext, run001.phi Warning messages: 1: No tidyselect variables were registered 2: Failed to create run summary.

I'm running dplyr version 0.8.4, xpose version 0.4.7 and R version 3.6.2 with R Studio, under Windows 10. I've tried it with and without the NOAPPEND in the $TABLE records. Any suggestions would be appreciated.
