installed sc-im-git with yay on manjaro linux, enabled 'xlsx_readformulas' but the (very simple) sum() formula from my xlsx file is not being read

So I installed sc-im w. yay on manjaro linux:

sc-im - version 0.8.4
-DNCURSES
-DMAXROWS 65536
-DUNDO
-DXLSX
-DXLUA
-DDEFAULT_COPY_TO_CLIPBOARD_CMD="xclip -i -selection clipboard <"
-DDEFAULT_PASTE_FROM_CLIPBOARD_CMD="xclip -o -selection clipboard"
-DDEFAULT_OPEN_FILE_UNDER_CURSOR_CMD="scopen"
-DUSELOCALE
-DMOUSE
-DUSECOLORS
-D_XOPEN_SOURCE_EXTENDED
-D_GNU_SOURCE
-DSNAME="sc-im"
-DHELP_PATH="/usr/share/sc-im"
-DLIBDIR="/usr/share/doc/sc-im"
-DDFLT_PAGER="less"
-DDFLT_EDITOR="vim"
-DCONFIG_DIR=".config/sc-im"
-DCONFIG_FILE="scimrc"
-DHISTORY_DIR=".cache"
-DHISTORY_FILE="sc-iminfo"
-DINS_HISTORY_FILE="sc-iminfo"
-DHAVE_PTHREAD
-DAUTOBACKUP

and I made a scimrc file with this content:

set autocalc
set numeric
set numeric_decimal=0
set overlap
set xlsx_readformulas

But when I open my very simple spreadsheet with some SUM() formulas, created by myself in libreoffice, the cells with SUM() are not being updated when deleteing numbers in the cells that they sum over.

I can see you need to add xlsx import/export functionality by building it on Ubuntu, but have not found any similar thing for arch-based distros, which leads me to believe that it is already present in the build files. What am I missing here? Sorry if there is some sort of tacit knowledge I'm suppose already have, but I simply can't see what I'm doing wrong here.

(also tried the non-git version w. yay: yay -S sc-im, also no luck)
