acronym first use not recognized in xltabular

[DaveInWellesley]

When using xltabular (or tabularx, I believe), the first use of an acronym is not recognized, so each occurrence in a table gets its own footnote. If the acronym has been used prior to being used in a table, the usage in the table does not result in additional footnotes.

I have attached a minimum working example.

And thanks for this very useful package!

Duplicate of #11.
Some environments, like tabularx, cannot handle macros with side effects. The only chance to consistently get the same result in such environments is to use the side-effect-free macros of this package, like \acs, \acl, or \acf.

So, after reading posts for #11 and #6 the underlying problem is much clearer. Thanks for your response.
