Export to .mp4 suddenly file size increase

[jurgiss40407612]

Dear members

Yesterday I was making an .AEP project, 1080x1080px, 50fps, 15 sec. The file size was about 18mb. 
I used Adobe media encoder, 10-12 mbs bitrate. 

Today I made some corrections in video, and Media encoder renders file size 90mb. 

I updated all Adobe products, changed renderer (hardware/software), changet bitrate, changet fps 50 to 25, and all the time file size is the same 87-90 mb. If  I export to uncompressed format(avi) and then export it with the same settings in adobe media encoder - everything is ok (18 mb).  But if to export directly - additional 70 mb connects to the file. Perhaps thats can a result of windows or adobe producs update.

Maybe you had simmilar issues?

I've just opened big file with hex viever.
Inside the file the biggest part of it is  sort of xml or xmp document, all lines begins with <rfd:li>
<rdf:li>6900273286F158D4C45E1E4347300F87</rdf:li>

I guess that's a bug of renderer, it adds 70 mb of strange information inside a file
