can you screen shot the zapier workflow? There is a good chance I can help if I see that, as I have like a bajillion zaps and have done probably more zapier work/troubleshooting than most anybody besides their employees I feel. Like, anyone using it like I do probably should learn to code…
Have you asked Zapier? My experience has been they are prompt and helpful. But I’m a paying user of zapier; not sure if there are free tiers that don’t have support.
These look like primary key field values to me?
I am assuming here that you are trying to send values that are from Link fields (or the key field from the current record) - although these look like they contain text, they actually store a key value. In order to get the value you want, you need to add a Lookup field to your table to get the value as text from the linked table (and sometimes a Formula if you want to create the value you need from several fields.)
Feel free to get back if you have more questions.
