Hello and thank you for contacting the Toolset support.
If I understood well, the Testimonials CPT from the Astra theme does not appear on the UAE posts widget, right? In that case, I don't see how Toolset is involved! Can you deactivate Toolset plugins and check if the issue still persists? If yes, I'll suggest reaching the UAE support or Astra support for assistance.
If the Testimonials CPT is built using Toolset, can you reproduce this issue on our test site? If yes, I'll escalate this issue to our 2nd Tier for further analysis before involving our compatibility team.
Please install the required plugins on this test install, create the CPT, and check if the issue is reproduced. hidden link
