as_word and gtsave seem to be adding an "X" at the end of the caption in the word file

Description

as_word and gtsave seem to be adding an "X" at the end of the caption in the word file. Please see the example below. I am using gt version gt_0.10.1

Reproducible example

gt(head(iris)) |> tab_header(title="Caption for table") ->t
gtsave(t,"temp.docx")

Expected result

The code should produce a caption like:

Table 1: Caption for table

But instead, it produces:

Table 1: Caption for tableX
