Memory used by read_xlsx

I have 4 xlsx files that I imported into R using read_xlsx, but they left something on the memory and I don't know if it is a known problem or am I doing something wrong. My code is simple

list <- list(
  file1 = read_xlsx("file1.xlsx"),
  file2 = read_xlsx("file2.xlsx"),
  file3 = read_xlsx("file3.xlsx"),
  file4 = read_xlsx("file4.xlsx")

The files are small (60.8MB, 0.8MB, 1.1MB and 61.1MB) but look at the memory report before and after the execution:

Here is my sessionInfo():
