Update to new template Error about kalnia-typeface HOT 1 CLOSED

On local, I could export the fonts, but after installing fontmake 3.4.0 and deleting the meta table (I did this just in local).
The error that I got from the meta table is:

File "/Users/fridamedrano/Desktop/Github/Test-2023-Sep11/Kalnia-Color/venv/lib/python3.11/site-packages/glyphsLib/builder/custom_params.py", line 573, in to_ufo_meta_table
tag, data = entry["tag"], entry["data"]
~~~~~^^^^^^^
TypeError: string indices must be integers, not 'str'

In my local files, I deleted the meta table, but it's still up in this Git Hub repo.
In the glyphs file software, the meta table appears as empty but the code from the glyphs file says:

name = "meta Table";
value = "{\012 data = Latn;\012 tag = dlng;\012}\012{\012 data = Latn;\012 tag = slng;\012}";
