This one is making me crazy. Using macOS High Sierra 10.13.4, FMPA 16.0.05.500. Two files - one the container field behaves as expected, 2nd file it does not. Same format settings on both. I use container fields frequently and have never seen this. When control-click on container field to bring up option menu, two completely different results. For ease of explanation attached are screen shots. File 1 behaves as all the rest do and is correct. File 2 does not. Both files have been in use for years and are unfortunately large and mission critical .So this is an unexpected result.
Thanks in advance for any advice or insight.
