@akolinski thanks for the report!

Can you specify under what conditions this show up, what are the necessary steps to replicate this?

If not sure about that, then what columns (and for what fieldtypes) are set to be displayed in the entry manager? And how does the URI string look like?

[akolinski]

@intoeetive I have updated my initial bug report above with the conditions it showed up under a heading called How To Reproduce. I have also listed all the deprecated errors and warnings appearing plus attached a log of the errors for your review and resolution.

[akolinski]

@intoeetive so will this be updated in the next EE release? Do you have an ETA on the next release?

[intoeetive]

The milestone for this is set to 7.3.14, which we plan to release next week - but we don't have fixed ETA
