rbind DHS data labelled - rbind

Question

For the context: For downloading DHS data I follow this link: https://rspatialdata.github.io/dhs-data.html#Loading_datasets_and_associating_its_metadata_into_R
I want to analyze it following this post: https://github.com/DHSProgram/DHS-Indicators-R/commit/1c64b0f2af33ac56d149a7dbce34ea8bb21ce3f9
Since I have data from 5 countries, starting in 2000 I joined HW files to PR files, where the orginal PR files did't have the hc (undernourishment) variables. The merge of HW files to PR files ended up the comb_extract_HW_res dataframe. However, when I want to bind my comb_extract_HW_res to the other dataframes (which files already included the hc variables) comb_extract by rbin_labelled (as I did for example to create comb_extact and everything just worked fine). But in this step (combining comb_extract which already contained hc variables and comb_extract_HW_res, where I added the variables) I somehow loosing all my negative values of my hc variables. Someone have an idea how this happens?
comb_extract_all <- rbind_labelled(list(comb_extract, comb_extract_HW_res), labels = list(hv023 ="concatenate", hv024 = "concatenate", hc70 = "concatenate", hc71 = "concatenate", hc72 = "concatenate", hc73 = "concatenate"))
my two dfs are:
