Appears to regenerate all slides when asking for a simple text update

I asked Context AI to remove a string of text present in all slides (global change, remove text). It acknowledged it, then proceeded to re-generate all slides (burning a ton of credits in the process).

It should really have the ability to just remove text with keeping the rest of the slides intact. Not happy about the burned credits and re-generating of the slides (it re-formatted / styled every element in the process, not what I needed).
